Background: Splenic cysts are uncommon and very rarely malignant therefore their treatment isn't standardized. In case of symptomatic cysts different surgical approaches have been suggested. Primary malignant lymphoma of the spleen comprises less than 1% of non-Hodgkin's lymphomas. To our knowledge, only 203 cases of splenic large B-cell lymphoma (LBCL) have been reported to date and only 2 of them were fibrin-associated splenic cysts. Case presentation: 27-year-old model with a 19 × 13 cm splenic cyst without data of malignancy in the preliminary study and therefore treated with laparoscopic deroofing. After histological diagnosis of LBCL with a fibrin/EBV-associated splenic pseudocyst, the patient received 4 cycles of Rituximab and a laparoscopic splenectomy was performed due to resurgence of the pseudocyst. No evidence of malignancy has been found during follow up (EBV viral load every 3 months during the first year, PET-CT every 6 months during the first year and annual afterwards) performed after the splenectomy. Discussion and conclusions: The value of tumor markers and radiology for diagnosis of splenic cysts is put into question. Only 60 cases of Fibrin-associated LBCL (FA-LBCL) have been described in the literature therefore there are no treatment guidelines for them even though surgery together with systemic treatment has been the prevalent route with good results in most cases.

Objectives: Pendred syndrome, an autosomal recessive disorder, is often associated with pathogenic variants of the SLC26A4 gene that encodes the pendrin protein. Given its autosomal recessive inheritance, tracing the family history and screening siblings become crucial once a diagnosis of Pendred syndrome is confirmed. This case report aims to underscore the variability in inner ear morphology within a family diagnosed with Pendred syndrome, all carrying the same SLC26A4 gene mutation. Methods: A chart review and a review of the literature. Results: We present a family of 4, all of whom possess sensorineural hearing loss due to the same homozygous SLC26A4 variant c.919-2A>G. Intriguingly, clinical manifestations, especially inner ear deformities, displayed variability among family members. Notably, 1 family member exhibited a normal cochleovestibular structure morphology, which was rarely reported in the literature. Conclusions: This report highlights the significance of genetic testing and familial consultation when a proband exhibits typical Pendred syndrome symptoms. It also underscores that the inner ear morphology can exhibit variability among family members, even with the same homozygous SLC26A4 variant. [ABSTRACT FROM AUTHOR]

Purpose: Children diagnosed with suprasellar arachnoid cysts often concurrently have hydrocephalus. This study aims to classify the relationship between suprasellar arachnoid cysts and hydrocephalus, discussing surgical strategies—shunting or neuroendoscopic approaches—and their sequence, based on this classification. Methods: A retrospective analysis was conducted on 14 patients diagnosed with suprasellar arachnoid cysts and hydrocephalus, treated surgically by the first author between January 2016 and December 2020. Clinical features, radiological findings, surgical strategies, and outcomes were reviewed. The classification of the relationship between the suprasellar arachnoid cysts and hydrocephalus was developed and illustrated with specific cases. Recommendations for future surgical management based on this classification are provided. Results: We classified the relationship between suprasellar arachnoid cysts and hydrocephalus into three categories. SACH-R1, the direct type, represents cases where the cysts cause obstructive hydrocephalus. Here, neuroendoscopic ventriculocystocisternostomy (VCC) effectively treats both conditions. SACH-R2, the juxtaposed type, involves concurrent occurrences of cysts and hydrocephalus without a causative link. This is further subdivided into SACH-R2a, where acute progressive communicating hydrocephalus coexists with the cyst, initially managed with a ventriculoperitoneal shunt, followed by VCC upon stabilization of hydrocephalus; and SACH-R2b, where the cyst coexists with chronic stable communicating hydrocephalus, first addressed with VCC, followed by monitoring and potential secondary shunting if needed. Key factors differentiating SACH-R2a from SACH-R2b include the patient's age, imaging signs of fourth ventricle and cisterna magna enlargement, and the rapid progression or chronic stability and severity of hydrocephalus symptoms. SACH-R3, the reverse type, describes scenarios where shunting for hydrocephalus leads to the development or enlargement of the cyst, managed via neuroendoscopic VCC with precautions to prevent infections in existing shunt systems. Conclusion: The simultaneous presence of suprasellar arachnoid cysts and hydrocephalus requires a nuanced understanding of their complex relationship for optimal surgical intervention. The analysis and classification of their relationship are crucial for determining appropriate surgical approaches, including the choice and sequence of shunting and neuroendoscopic techniques. Treatment should be tailored to the specific type identified, rather than blindly opting for neuroendoscopy. Particularly for SACH-R2a cases, we recommend initial ventriculoperitoneal shunting.

Cyst excision and Roux-en-Y hepaticojejunostomy (RYHJ) is the standard treatment for choledochal cysts (CCs). In the present study, the results of totally laparoscopic surgery for CCs (TLCCs) in a pediatric population were evaluated. The clinical data of 28 children with CCs between June 2020 and June 2023 were retrospectively reviewed. All patients underwent TLCCs involving cyst excision and RYHJ. The jejunojejunal anastomosis was completed laparoscopically using manual sutures. Age at operation, operative time, postoperative recovery and complications were evaluated. The 28 patients comprised 8 boys and 20 girls who underwent TLCCs at a mean age of 4.2 years (range, 1 month-12.3 years) with a mean weight of 15.9 kg (range, 4.6-43 kg). All patients received ultrasound and magnetic resonance cholangiopancreatography examinations, which revealed a mean cyst diameter and length of 1.74±0.76 cm and 3.85±1.25 cm, respectively. The mean operative time was 214±43.8 min. The mean time until starting an oral diet after surgery was 2.89±1.23 days. Apart from bile leakage and wound infection, no other complications occurred during a median follow-up period of 18 months (range, 4-42 months). TLCCs can be performed safely by skilled surgeons in pediatric patients. TLCCs may be more physiologically compatible and accelerate recovery of intestinal function with reduced trauma and better esthetic outcomes than conventional laparoscopic surgery for CCs. Therefore, TLCCs with manual sutures may be considered as an option for minimally invasive surgery in pediatric patients with CCs. [ABSTRACT FROM AUTHOR]

Objectives: To document the case of a patient who underwent several endodontic treatments due to a glandular odontogenic cyst misdiagnosed as an inflammatory periapical lesion. Background: Glandular odontogenic cysts behave more aggressively, while others have an indolent course. There is limited information on this cyst in the gerodontologic literature. Materials and Methods: A 76‐year‐old male patient presented with an asymptomatic expansive lesion in the anterior mandible resistant to several endodontic treatments. Cone‐beam computed tomography revealed a multilocular osteolytic lesion measuring 6.0 × 4.0 cm, with cortical bone perforation. Results: Histopathological analysis of a biopsy specimen was consistent with glandular odontogenic cyst. The patient underwent marginal mandibulectomy with preservation of the base of the mandible. Conclusion: A strict diagnostic process is important to avoid unwanted consequences, particularly in the geriatric population. [ABSTRACT FROM AUTHOR]

Background: We conducted this study to clarify the magnetic resonance imaging (MRI) characteristics of lobular endocervical glandular hyperplasia (LEGH) and Nabothian cysts. Methods: This study included 48 patients who underwent hysterectomy at our institution between 2016 and 2020 for suspected LEGH. Histopathological studies confirmed the presence of 25 Nabothian cysts and 23 cases of LEGH. We retrospectively analyzed five characteristic MRI findings: (1) located at the upper cervical canal, (2) positioned within the cervical stroma, (3) not circumscribing the cervical canal, (4) low- to iso-intensity on T1-weighted images (T1WI), and (5) "cosmos" or "microcystic" pattern. We compared the diagnostic accuracy of these findings for LEGH and Nabothian cysts using sensitivity, specificity, and predictive values. Combinations of findings were also calculated. Results: The characteristics "cosmos" or "microcystic" pattern, lesion not circumscribing the cervical canal, and low/iso-intensity on T1WI had a sensitivity and specificity greater than 50%. The sensitivity was 73.9% and specificity 84.0% when a combination of "cosmos" or "microcystic" pattern and lesion not circumscribing the cervical canal was present. Conclusion: The coexistence of a "cosmos" or "microcystic" pattern and not circumscribing the cervical canal was the most characteristic finding that distinguished LEGH from Nabothian cysts. When neither of these findings is present, Nabothian cyst can be suspected. [ABSTRACT FROM AUTHOR]

Background: Tubal mesosalpinx cysts are paratubal cysts, that account for approximately 10% of adnexal masses, and the presence of these cysts combined with adnexal torsion is a rare acute abdominal condition, with few cases reported in the literature. We reported two cases of adolescent tubal mesosalpinx cysts combined with adnexal torsion and reviewed the literature to help improve the diagnosis of the disease. Case reports: The first patient was an 11-year-old girl with left lower abdominal pain for 5 days and fever with nausea and vomiting for 3 days, who was found to have a cystic pelvic mass on preoperative imaging and was diagnosed intraoperatively and postoperatively on pathology as having a left tubal mesosalpinx cyst combined with adnexal torsion. The second patient was a 13-year-old girl with right lower abdominal pain for 16 h and a palpable mass in the lower and middle abdomen on examination, which was hard and tender to palpate. Preoperative imaging revealed a large cystic mass in the right adnexal region, and intraoperative and postoperative pathology revealed a right tubal mesosalpinx cyst combined with adnexal torsion. Conclusions: Tubal mesosalpinx cysts combined with adnexal torsion are rare causes of acute lower abdominal pain. Early diagnosis and timely surgery are necessary to ensure ovarian and tubal function. Accurate preoperative imaging diagnosis is challenging, and MRI is a beneficial supplement to ultrasound and CT examinations, providing more objective imaging information and reducing the incidence of adverse outcomes.

Background: Deep angiomyxoma (DAM) is a slow-growing benign tumor with high risk of local recurrence after surgical resection. Although DAM in a lower extremity is extremely rare, clinicians must be aware of its possible occurrence. Suspicion can be made based on clinical examination and radiological imaging but final diagnosis is confirmed on histopathological examination and immunohistochemistry. We intend to present an extremely rare case of DAM in the knee, managed successfully with marginal excision. Case Presentation: A 4-year-old male child presented with the complains of a painless, progressively increasing, soft, non-tender, and fluctuant swelling in his right knee. The plain radiograph showed a non-calcified soft-tissue swelling and MRI revealed a multi-loculated cystic lesion with multiple septations. A pre-operative diagnosis of a benign cystic lesion was made. It was managed by marginal excision of the tumor and a histological diagnosis of DAM was made. IHC staining showed positivity for SMA, CD34 and vimentin were focally positive, while desmin and calponin were negative. At 12 months of follow-up, the patient had a normal painless gait and full knee ROM, without any local recurrence. Conclusion: DAM is a rare tumor which is often misdiagnosed. In this report, we present a rare case of benign cystic lesion which turned out to be DAM on HPE of resected specimen. Marginal excision of this lesion revealed good outcomes with no recurrence until 12 months of final follow-up. With this, we conclude that surgical excision should be the gold standard in cases of DAM. [ABSTRACT FROM AUTHOR]

Though aetiology of lateral neck masses is complex, branchial cleft cyst is the second most common congenital lesions of the neck next only to thyroglossal duct cysts. Rarely ectopic thyroid tissue within a branchial cleft cyst may develop into primary papillary carcinoma, and even more rarely it may harbour metastases of primary thyroid papillary carcinoma. We report a rare case of lateral cystic neck mass in a 24-year-old female patient diagnosed as metastatic PTC. The patient was diagnosed after she underwent surgical excision of branchial cleft cyst. Later prospectively the patient underwent total thyroidectomy which revealed papillary thyroid micro invasive carcinoma. [ABSTRACT FROM AUTHOR]

Introduction: Recurrence is a major challenge in the treatment of solitary bone cysts (SBC). In this study, we aimed to analyze the factors that influence the risk of recurrence in patients with simple bone cysts. Methods: The study included patients who underwent curettage and bone grafting for SBC between 2010 and 2021 at a single center. Data collected included age, sex, side, bone location, pathological fracture history, cyst activity, internal fixation, graft type, radiological features of the cyst (cyst index, cyst diameter ratio, cyst area and cyst length), follow-up time, and presence of recurrence. The Cox algorithm was applied to identify factors independently associated with SBC recurrence. Results: A total of 41 patients with a mean age of 10.8±3.19 years (range 4-15 years) were included in this study. The average follow-up period was 51±21.3 months. Recurrence was observed in 13 of 41 patients during follow-up. There were no significant differences in sex, bone location, pathological fracture history, and the type of graft used between patients with and without recurrence. The age at surgery was found to be significantly lower in the recurrence group (p=0.02). The radiological features of the cyst: cyst index, cyst diameter ratio, cyst area, and cyst length, were found to be higher in the recurrence group, although there was no significant difference. Conclusion: It is important to inform families that the risk of recurrence is high at a young age and in patients with large solitary bone cysts. [ABSTRACT FROM AUTHOR]

Purpose: Meningioma is the most common intracranial tumor, graded on pathology using WHO criteria to predict tumor course and treatment. However, pathological grading via biopsy may not be possible in cases with poor surgical access due to tumor location. Therefore, our systematic review aims to evaluate whether diagnostic imaging features can differentiate high grade (HG) from low grade (LG) meningiomas as an alternative to pathological grading. Methods: Three databases were searched for primary studies that either use routine magnetic resonance imaging (MRI) or computed tomography (CT) to assess pathologically WHO-graded meningiomas. Two investigators independently screened and extracted data from included studies. Results: 24 studies met our inclusion criteria with 12 significant (p < 0.05) CT and MRI features identified for differentiating HG from LG meningiomas. Cystic changes in the tumor had the highest specificity (93.4%) and irregular tumor-brain interface had the highest positive predictive value (65.0%). Mass effect had the highest sensitivity (81.0%) and negative predictive value (90.7%) of all imaging features. Imaging feature with the highest accuracy for identifying HG disease was irregular tumor-brain interface (79.7%). Irregular tumor-brain interface and heterogenous tumor enhancement had the highest AUC values of 0.788 and 0.703, respectively. Conclusion: Our systematic review highlight imaging features that can help differentiate HG from LG meningiomas. [ABSTRACT FROM AUTHOR]

"Cysts of the ligamentum flavum (cysts‐LF)" is the term for non‐neoplastic cystic lesion involving LF. The aim of the present study was to elucidate the histopathological characteristics and pathogenesis of "cysts‐LF". Herein, we defined cysts‐LF as spinal cysts containing degenerative LF components. From archival cases, we investigated 18 symptomatic cysts‐LF surgically removed from 18 patients (13 males and five females; median age 68.5 years [range, 42–86 years]). The elastic fibers of LF components in the wall were separated and/or torn, and cyst walls were accompanied by chondroid metaplasia (17 cases), myxoid changes (13 cases), ossification (11 cases), amyloid deposits (14 cases), hemosiderosis (six cases), granular/smudgy calcification (four cases), synovial cell linings (three cases), and severe inflammatory infiltrates (one case). These histologic features of our cysts‐LF were shared by previously reported "cysts‐LF." Fourteen cysts‐LF demonstrated vascular stenosis/occlusion, and eight showed thick hyalinized vessels, suggesting local circulatory insufficiency. Eight cases (44%) exhibited lipomembranous fat necrosis, accompanied by hyalinized vascular changes (p = 0.003). Ischemic conditions were observed in nearly half of the present cysts‐LF, and may be one of the main contributing factors for the formation of cysts‐LF, via degeneration and cystic changes in the LF.

Introduction and importance: Choledochal cysts are congenital conditions that affect the biliary tree, typically identified during childhood. These cysts present as dilations in the biliary system, occurring either in the extrahepatic or intrahepatic regions or in some cases, in both areas. Occasionally, it may have associated chronic pancreatitis posing a challenge to the management of both conditions. In the case reported, a female child was diagnosed with a choledochal cyst along with chronic pancreatitis. She had an excision of cyst and lateral pancreaticojejunostomy simultaneously for both conditions resulting in favorable outcomes. Case presentation: An 8-year-old child visited the clinic with a complaint of upper abdominal pain accompanied by intermittent vomiting. An ultrasound was performed which showed a dilated common bile duct. To confirm the diagnosis, an MRCP and baseline labs including liver function tests were ordered. The findings were suggestive of a type IA choledochal cyst with concomitant chronic pancreatitis. Subsequently, she had choledochal cyst excision with Roux-en-Y hepaticojejunostomy reconstruction plus lateral pancreaticojejunostomy using the classical Puestow's technique. The patient's recovery post-surgery was uneventful, resulting in discharge on the fifth post-operative day for routine outpatient follow-up. Clinical discussion: Patients afflicted with choledochal cysts are prone to recurrent pancreatitis, though the precise underlying mechanism is unknown. Certain studies propose an association between abnormal pancreatico-biliary junction and recurrent pancreatitis, often defined as a common channel surpassing 15 mm in length. However, this aberration could not be definitively established in the current case. Diagnosis of choledochal cysts can be confirmed through either ERCP or MRCP, with the latter preferred due to its non-invasive nature. The optimal management strategy for choledochal cysts necessitates cyst resection and Roux-en-Y hepaticojejunostomy reconstruction Moreover, in cases associated with chronic pancreatitis, longitudinal pancreatojejunostomy may be undertaken. Conclusion: Thus, it is concluded that although rare choledochal cysts may have associated chronic pancreatitis. Surgical excision of the cyst and lateral pancreaticojejunostomy can be performed simultaneously resulting in favorable post-operative outcomes. [ABSTRACT FROM AUTHOR]

Objective: Laparoscopic choledochectomy and hepatojejunostomy have been reported in children since 1995, but this procedure is technically demanding. Robotic surgical systems can simplify complex minimally invasive procedures. Currently, few reports have been made on neonates. We present the experience of 6 cases of neonatal CC(choledochal cysts). Study design: Between January 2022 and December 2023, 6 neonates underwent robotic resection of choledochal cyst and hepaticojejunostomy using the Da Vinci surgical system at Children's Hospital, Zhejiang University School of Medicine, a high-volume hepatobiliary disease center. demographic data of the patients and surgical outcomes were collected and analyzed. Results: All 6 patients were successfully treated by robotic cystectomy and hepaticojejunostomy. The mean age was 17.3 days (range 4–25) and the mean weight was 3.6 kg (range 2.55–4.4). 5 cysts were type Ia and 1 was type Iva. The mean diameter of the cysts was 3.8 cm (range 1.25-5). The mean time to establish feeding was 4.83 days (range 4–6), and patients were discharged after a median time of 16.83 days (range 7–42) without postoperative complications. Conclusions: This procedure is safe and effective for neonates. The authors found that the use of robot-assisted surgery has ergonomic advantages in this delicate, minimally invasive procedure.

Background: Primary cardiac tumors, while rare, present significant clinical challenges due to their diverse pathology and presentation. Lung cancer frequently metastasizes to the heart; however, cases involving primary cardiac tumors of different origins alongside primary lung cancer are exceedingly rare in the literature. Case presentation: We report the case of a 53-year-old female who presented with hemoptysis and was subsequently diagnosed with a left atrial myxoma, pulmonary squamous cell carcinoma, and a thymic cyst. This coexistence of multiple non-homologous tumors in a single patient is exceedingly rare. Conclusion: This case underscores the complexity of diagnosing and managing patients with multiple distinct tumors. The simultaneous occurrence of a primary cardiac myxoma, pulmonary squamous cell carcinoma, and thymic cyst is unprecedented, providing valuable insights for future clinical practice.

Purpose: To describe clinical features of choledochal cyst (CC) patients in terms of demographic data, clinical presentation, investigations, treatment, and outcomes among children and adults. Methods: The medical records of patients undergoing choledochal cyst (CC) surgery from 2002 to 2021 at a university hospital were retrospectively reviewed. The patients were divided into two groups: children (< 15 years) and adults (≥ 15 years). Descriptive statistics were used. Results: There were 106 cases of CC (Female/male = 88/18, children/adult = 53/53). Abdominal pain was the predominant presenting symptom, followed by jaundice in both groups. Adults were significantly more prone to present with abdominal pain compared to children (86.8% vs. 52.8%; p < 0.001), while children were more likely to experience acholic stool than adults (22.6% vs. 3.8%; p = 0.004). Ultrasound was the preferred investigation screening modality (75.5%). Most patients were presented with type I CC (71.7%). Laparoscopic-assisted approach was performed in 8.5%. CC excision with roux-en-y hepatico-jejunostomy was the main procedure (88.7%). Adults had a higher incidence of post-op complications, including stones, anastomosis stricture, abdominal collection, and cholangitis. Adults were significantly more likely to require intervention after surgery, compared to children (26.4% vs. 5.7%; p = 0.04). Conclusions: Ultrasound was the most common screening tool for diagnosis. Postoperatively, adults with CC experience more serious post-op complications compared to children. This could be attributed to long-standing cystic inflammation. Therefore, prompt definitive surgery is recommended for CC patients. [ABSTRACT FROM AUTHOR]

Adeloye-Odeku disease was initially reported as an African congenital cyst in 1971, but this disease is now been documented worldwide. Adeloye-Odeku disease is classified as a congenital subgaleal inclusion dermoid cyst of the anterior fontanelle region. Mostly, this disease occurs in infants or children. This is the first case report of Adeloye-Odeku disease in Indonesia. The case report of a 5-month girl is presented with a lump that had developed since birth. The characteristic of lump was soft, non-tender, dome-shaped, and positive transillumination results. A computed tomography (CT) scan was carried out, with the result of a subgaleal dermoid inclusion cyst in the anterior fontanelle region. The anterior fontanelle appeared widened without intracranial expansion. Surgical excision of the cyst was performed under general anesthesia successfully. Histopathologic examination showed dermoid cysts without malignancy features. There were no complications reported when the patient attended the follow-up visit at the outpatient clinic. This is consistent with the existing literature on Adeloye-Odeku disease. [ABSTRACT FROM AUTHOR]

Adrenal cysts are a rare benign adrenal pathology. Although the majority of adrenal cysts are asymptomatic, large cysts may present with debilitating symptoms of mass effect. Surgical adrenalectomy or cyst fenestration has been the primary mode of management for such symptomatic cysts, but these interventions can be associated with excessive morbidity, particularly when considered in the context of benign disease. Here, we present a case of a 34-year-old female with a longstanding, growing, benign left adrenal cyst associated with nonspecific abdominal symptoms. After multidisciplinary discussion, the patient was managed with primary ultrasound/fluoroscopic guided percutaneous sclerotherapy of her adrenal cyst. This technique achieved complete cyst resolution that was durable on 7-month follow-up and was associated with significant improvement of the patient's symptoms. This case illustrates the potential for primary percutaneous sclerotherapy for primary management of benign adrenal cysts. [ABSTRACT FROM AUTHOR]

Esophageal duplication cysts are rare congenital noncancerous growths. Symptoms of this disease are reported to be asymptomatic in approximately 70% but include respiratory symptoms such as coughing and difficulty breathing. Minimally invasive removal of these cysts without esophagectomy is typically recommended. However, when the cyst is situated in the upper mediastinum, surgical excision becomes technically challenging. Here, we report a case of an obese female patient with esophageal duplication cyst in the upper mediastinum who underwent successfully robotic‐assisted complete removal of the cyst. A 50‐year‐old woman presented to a local clinic with a persistent cough and hoarseness lasting 4 months. A computed tomography scan revealed a large cystic tumor in the upper mediastinum, causing displacement of the trachea. The resection of the cystic tumor was safely performed with robotic assistance. The use of robotic system for the removal of esophageal duplication cyst is technically safe and feasible. [ABSTRACT FROM AUTHOR]

Laparoscopic fenestration is the preferred treatment for symptomatic splenic cysts because it is curative and spleen‐sparing. We report a case of a 25‐year‐old female who underwent laparoscopic fenestration for a giant splenic cyst using a single‐incision plus one‐port approach. She presented to our hospital with repeated vomiting. Imaging showed a 23 × 18 cm splenic cyst with no solid components, strongly compressing the stomach to the right side. Laparoscopic fenestration was initiated through a 2.5‐cm umbilical incision, and a 5‐mm port was added in the left abdomen intraoperatively. The drain placement was deemed necessary to prevent abscess formation and post‐operative bleeding because of a thick cyst component and unexpectedly thick wall. Splenic cysts are typically benign and commonly develop in young people, hence, organ preservation and cosmetic results are crucial. Laparoscopic fenestration using single‐incision plus one‐port is considered to be an appropriate procedure for giant splenic cysts with non‐serous contents. [ABSTRACT FROM AUTHOR]

Laparoscopic deroofing (LD) for giant liver cysts using indocyanine green (ICG) fluorescence imaging was performed in two patients: a 53‐year‐old man with a 26‐cm, symptomatic cyst and a 50‐year‐old woman with a 13‐cm, symptomatic cyst. ICG fluorescence imaging can be used to easily identify the boundary between the liver parenchyma and the liver cyst. No postoperative bile leakage was observed in both patients. ICG fluorescence imaging is expected to become a desirable procedure in LD for giant liver cysts to reduce the occurrence of perioperative complications. [ABSTRACT FROM AUTHOR]

The treatment of symptomatic Tarlov cysts remains a controversial topic within neurosurgery. We describe our experience with patients who underwent surgical intervention for sacral Tarlov cysts at a single institution. General and disease-specific outcome measures were used to assess health-related quality of life. Patients who underwent surgical treatment for one or more sacral Tarlov cysts between 2018 and 2021 were included. The Tarlov Cyst Quality of Life (TCQoL), a validated disease-specific measure, was the primary outcome of the study. Secondary outcomes included general outcome measures: 36-Item Short Form Survey, the Oswestry Disability Index, and Visual Analog Scale. Patients were followed at 3, 6, and 12 months postoperatively. Repeated measures analyses were used to assess change from preoperative to 12 months postoperative. Data were obtained from 144 patients who underwent surgery for sacral Tarlov cysts, average age 52.3 ± 11.3 years, 90.3% female. Patients reported significant mean improvement on the TCQoL over time (preoperative 3.2 ± 0.1; 3-month postoperative 2.1 ± 0.1; 6-month 1.9 ± 0.1; 12-month 1.9 ± 0.1; P < 0.001). Patient age and duration of symptoms were not associated with outcome. A total of 82.3% of patients reported improvement on TCQoL. There was not a significant difference in the proportion of patients reporting improvement on TCQoL by cyst size (small 90.9% vs. large 77.9%; P = 0.066). Our longitudinal series demonstrated patient-reported improvement following surgery for symptomatic sacral Tarlov cysts using a validated disease-specific health-related quality of life scale through 12 months after surgery. Patient age and preoperative duration of symptoms were not correlated with outcome. [ABSTRACT FROM AUTHOR]

Although various treatment options are available for spinoglenoid cyst, including conservative and surgical methods, there is no standard guideline for its surgical decompression. Thus, the purpose of the study was to correlate the size of the spinoglenoid notch ganglion cyst (GC) as revealed by magnetic resonance imaging (MRI) with electrophysiological alterations, muscle power, and pain severity, and to estimate a cut-off value of cyst size to perform a decompression. Between January 2010 and January 2018, the patients with a GC at the spinoglenoid notch diagnosed on MRI, and who had a minimum follow-up of 2 years after the decompression were included. Maximum cyst diameter as measured on MRI was used for comparison. Electromyography (EMG) and nerve conduction velocity (NCV) studies were performed before the surgery. Peak torque deficit (PTD) percentage compared to opposite shoulder was calculated preoperatively and at 1 year after surgery. Pain severity was estimated using visual analogue scale (VAS) preoperatively. Ten (50%) of 20 patients with GC > 2.2 cm and 1 (5.9%) of 17 patients with GC < 2.2 cm showed EMG/NCV abnormalities (p = 0.019). There was a correlation between the cyst size and the positive EMG/NCV findings (Correlation coefficient (CC) = 0.535, p < 0.001). The preoperative peak torque deficit on the external rotation was correlated with the positive EMG/NCV findings (CC = 0.373, p = 0.021). The PTD was improved significantly at 1 year postoperatively in patients with a GC size >2.2 cm (p = 0.029). The cyst size was not related to the preoperative pain VAS and muscle power. The spinoglenoid cyst size >2.2 cm, but not pain severity or muscle power, correlates with the positive finding of EMG for compressive suprascapular neuropathy. The GC size >2.2 cm can be a reference to decide the need of decompression surgery. IV, case series. [ABSTRACT FROM AUTHOR]

Background: Surgical ciliated cysts occur mainly in the maxillae after radical maxillary sinus surgery; they rarely develop in the mandible. This study aims to gather information on all the characteristics of patients suffering from mandibular surgical ciliated cysts. This article also reports two new cases. Methods: PubMed, Google Scholar and the International Clinical Trials Registry Platform were explored until 13 December 2022 for articles regarding mandibular surgical ciliated cysts. Maxillary ciliated cysts were excluded. Results: Fourteen original articles were included in a total of 16 cases. Maxillofacial surgeries are the first aetiology (94.4%). Surgical ciliated cysts of the mandibular region show a 1.25:1 male‐to‐female ratio with a protracted time to diagnosis (range: 2–56 years). Most patients are symptomatic (77.8%). Typically, radiology shows a radiolucency lesion (88.9%) and histology describes pseudostratified ciliated columnar epithelium. Enucleation has always been described as the treatment. Discussion: All results were case reports, thus a low level of evidence studies. Mandibular surgical ciliated cysts should be considered in patients presenting a mandibular swelling or radiolucency lesion with a maxillofacial surgery history. Meticulous surgical techniques can aid in the prevention of this lesion. [ABSTRACT FROM AUTHOR]

Background: Oral mucoceles (OMs) are common cystic lesions seen mainly on the lower lip in young males. Histologically, OMs show variegated features such as clear cell changes, myxoglobulosis, calcifications, and papillary synovial metaplasia (PSM)‐like changes. The aim of the present paper is to morphometrically analyze PSM‐like changes seen in OMs. Methodology: Seventy‐two cases of histologically proven OMs were retrospectively retrieved and divided into two groups: group I without PSM‐like changes and group II with PSM‐like changes. The internal area was measured using Image J software. SPSS version 26 was used to analyze the data. Results: There were 50 cases in group I (mean age 19.23 years) and 22 cases in group II (mean age 30.25 years). The lower lip was the most commonly affected site for both groups. The mean age in group II was significantly higher than group I. In contrast, the mean internal area was significantly higher in group I. Conclusion: We speculate that PSM‐like changes in OMs represent an incomplete repair phenomenon. Knowledge of such an innocuous process is essential for differentiation from malignant histopathological mimickers. [ABSTRACT FROM AUTHOR]

An interosseous ganglion cyst is a very rare entity, found mostly in skeletally mature patients, particularly in long bones such as the tibia and femur. However, we are the first to report here an unusual case of interosseous ganglion cyst of the upper ribs in a young female patient, which she had an unpredicted presentation of cough and hemoptysis and a large painful lump over the anterior left upper chest. The radiological and pathological workup confirmed the presence of a benign interosseous ganglion cyst arising from the left first rib, invading the second rib and the apex of the left lung. The patient has been treated successfully by surgical resection of this rib cyst. However, we could not find any reported cases in the current literature of an interosseous ganglion cyst pathology arising in the ribs with a similar presentation of cough and hemoptysis.

Purpose: Symptomatic Tarlov cysts in children with a possible underlying one-way check-valve mechanism are very rare. We aim to introduce a new variation of the surgical technique to overcome a check-valve mechanism. Methods: A 15-years-old girl presented with double incontinence and anogenital numbness due to a large sacral Tarlov-cyst with possibly underlying one-way check valve mechanisms as suggested by preoperative computed tomography myelography. Intraoperatively, one-way check-valve was confirmed and could be eliminated by creating an artificial inner ostium between the Tarlov cyst and thecal sac with blunt perforation. Results: Postoperatively, the patient had established normal sphincter control and sensation in the anogenital region. Conclusion: One-way check-valve mechanism might contribute to the symptomatology of large sacral Tarlov cysts in children. Our new variation of a surgical technique enables elimination of the check-valve mechanism without the necessity to open and close the typically very thin and fragile cyst surface and is therefore an efficacious and simple option in this situation.

Summary: Potato production in East Africa is seriously impacted by the potato cyst nematode (PCN), Globodera rostochiensis , where it has been recorded in at least three countries. In Kenya, it is widespread in all major potato-growing regions, often at very high densities. Consecutive cropping of potato on the same land and a sub-tropical climate have influenced PCN biology. For example, unusually large cysts have been regularly recovered. We have analysed the biological properties of these 'giant cysts'. The giant cysts contained more eggs than those recovered from UK fields. Egg size did not differ from UK populations and there was no difference in overall lipid content or lipid profile in J2 from giant cysts, compared to control samples. The nematodes in giant cysts were also genetically indistinguishable from any other G. rostochiensis sampled. When grown under UK glasshouse conditions, the offspring of nematodes from giant cysts were no different in size from those grown from control cysts, indicating that gigantism is not a heritable trait and may simply reflect favourable conditions for PCN under Kenyan farming systems. To date, all the PCN tested from Kenya, including those from giant cysts, are avirulent on potato cultivars containing the H 1 resistance gene. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Tarlov cysts are uncommon causes of sacral radiculopathy, with particular predilection to second and third sacral roots, requiring timely diagnosis with lumbosacral MRI, and surgical management if symptomatic. Tarlov cysts or Type II meningeal cysts, are CSF‐filled sacs located in the extradural space of the sacral spinal canal, commonly originating at the dorsal root ganglion. While they were first documented by Tarlov in 1938, their etiology remains uncertain, with theories suggesting trauma‐induced bleeding or congenital abnormalities. These cysts, estimated to affect between 1% and 9% of the adult population, typically manifest as incidental findings but may lead to symptoms such as radiculopathies, sacral pain, and weakness in related sacral muscles. We present a case of a 63‐year‐old female presenting with recurrent left buttock pain and radiating leg discomfort. Physical examination revealed tenderness in the left buttock region, positive straight leg raise test, and minimal sensory deficits in the S1‐S2 dermatomes. A provisional diagnosis of radiculopathy was made, prompting further evaluation with MRI, revealing a Tarlov cyst and absence of lumbar spinal canal stenosis or neural foraminal compromise. The patient declined intervention and was managed conservatively. This case highlights the diagnostic challenges and therapeutic considerations in managing symptomatic Tarlov cysts, emphasizing the importance of tailored treatment strategies. [ABSTRACT FROM AUTHOR]

This study aimed to determine the prevalence of Cysticercus tenuicollis among 500 Red Sokoto goats slaughtered at the Akinyele abattoir in Ibadan between October and December. This period targeted the wet month, transition from rainy to dry season, and the dry month. Post-mortem examinations were conducted on goats for C. tenuicollis. Cysts that were recovered underwent identification based on their morphology, with both their number and location documented. The study found an overall prevalence rate of 38.2%. Among the 416 males and 84 females examined, 160 (38.5%) and 31 (36.9%), respectively, were found to be infected, with no significant differences observed between the sexes. Prevalence in October was 47.1% (106/225), November was 40.5% (75/185), and December was 11.1% (10/90), with higher rates in wet months transitioning to lower rates in dry months, with a significant association between prevalence and month. Among the 281 cysts identified, they were distributed across the liver (18, 6.4%), mesentery (98, 34.9%), and omentum (165, 58.7%). Notably, C. tenuicollis was most commonly found in the omentum, accounting for 58.7% of the cases. The distribution of cysts by location and the analysis of potential risk factors for sex and age showed a significant association with age but not with sex. Although more cysts were observed in males, the difference was not statistically significant. This study provides valuable baseline data on the prevalence of C. tenuicollis in goats during the study period. The high prevalence and distribution patterns identified can serve as crucial insights for designing effective control strategies, including targeted anthelmintic treatments and improving meat inspection protocols.

Background Tarlov cysts are perineural collections of cerebrospinal fluid most often affecting sacral nerve roots, which may cause back pain, extremity paresthesias and weakness, bladder/bowel dysfunction, and/or sexual dysfunction. The most effective treatment of symptomatic Tarlov cysts, with options including non-surgical management, cyst aspiration and injection of fibrin glue, cyst fenestration, and nerve root imbrication, is debated. Methods Retrospective chart review was conducted for 220 patients with Tarlov cysts seen at our institution between 2006 and 2021. Logistic regression analysis was conducted to determine the association between treatment modality, patient characteristics, and clinical outcome. Results Seventy-two (43.1%) patients with symptomatic Tarlov cysts were managed non-surgically. Of the 95 patients managed interventionally, 71 (74.7%) underwent CT-guided aspiration of the cyst with injection of fibrin glue; 17 (17.9%) underwent cyst aspiration alone; 5 (5.3%) underwent blood patching; and 2 (2.1%) underwent more than one of the aforementioned procedures. Sixty-six percent of treated patients saw improvement in one or more symptoms, with the most improvement in patients after aspiration of cyst with injection of fibrin glue; however, this association was not statistically significant on logistic regression analysis. Conclusion Although the subtype of percutaneous treatment was not significantly associated with optimal or suboptimal patient outcomes, cyst aspiration both with and without injection of fibrin glue may serve as a useful diagnostic tool to (1) determine symptom etiology and (2) identify patients who might have achieved temporary improvement between the time of cyst aspiration and refill with cerebrospinal fluid as potential candidates for neurosurgical intervention of cyst fenestration and nerve root imbrication.

Background: Cystic echinococcosis (CE), a helminth‐associated zoonosis caused by Echinococcus granulosus, poses a significant public health problem, particularly in pastoral‐rearing regions. The lack of uniform guidelines led to variations in CE management. Based on ultrasound data, the World Health Organization Informal Working Group on Echinococcosis (WHO‐IWGE) classification system categorizes cysts into active, transitional, and inactive groups. This study assesses whether the therapeutic approach from liver human operation cases in North Khorasan province aligns with the WHO‐IWGE reference based on ultrasound data. Methods: The research is based on ultrasound data from liver CE human operation cases collected between 2018 and 2022. This retrospective study investigates the therapeutic protocol for (CE) in North Khorasan Province, Iran, comparing it with the WHO‐IWGE guidelines. We collect data from previously registered patients' medical information from our studied area's main CE surgical hospital. Moreover, as the first hospitalized survey in Iran, this study reveals insights into patient demographics, cyst stage prevalence, and treatment modalities. Results: Notably, more than half of the patients were treated for CE1 stage cysts, and CE4 cases, which generally do not require surgery, underwent open surgery. The results suggest a need for adherence to the "watch‐and‐wait" approach in specific cases. All patients underwent successful surgeries, but we do not have access to follow‐up data from patients after discharge. Conclusions: This descriptive study contributes to understanding the implementation of WHO guidelines in a regional context, shedding light on the challenges and variations in CE management. It seems, retraining courses for surgeons are required to update their knowledge of standard CE diagnostic and treatment methods. Access the CME test here and search by article title.

Rathke’s cleft cysts (RCC) are a common type of lesion found in the sellar or suprasellar area. They are usually monitored clinically, but in some cases, surgery may be required. However, their natural progression is not yet well understood, and the outcomes of surgery are uncertain. The objective of this study is to evaluate the natural history of Rathke’s cleft cysts in patients who are clinically monitored without treatment, and to determine the outcomes of surgery and the incidence of recurrences over time. Design and patients: National multicentric study of patients diagnosed of Rathke’s cleft cyst (RCC- Spain) from 2000 onwards and followed in 15 tertiary centers of Spain. A total of 177 patients diagnosed of RCC followed for 67.3 months (6–215) and 88 patients who underwent surgery, (81 patients underwent immediate surgery after diagnosis and 7 later for subsequent growth) followed for 68.8 months (3–235). Results: The cyst size remained stable or decreased in 73.5% (133) of the patients. Only 44 patients (24.3%) experienced a cyst increase and 9 of them (5.1%) experienced an increase greater than 3 mm. In most of the patients who underwent surgery headaches and visual alterations improved, recurrence was observed in 8 (9.1%) after a median time of 96 months, and no predictors of recurrence were discovered. Conclusions: Rathke’s cleft cysts without initial compressive symptoms have a low probability of growth, so conservative management is recommended. Patients who undergo transsphenoidal surgery experience rapid clinical improvement, and recurrences are infrequent. However, they can occur after a long period of time, although no predictors of recurrence have been identified. [ABSTRACT FROM AUTHOR]

Introduction: Splenic cyst is a rare entity with very few cases reported in literature. The diagnosis is usually incidental on autopsy, associated with symptoms due to enlargement, rupture, infection, or hemorrhage. It can be of two types - parasitic or nonparasitic cyst. Case Report: Postmortem viscera of 33 year old male were received in the department of Pathology for histopathological examination. Grossly, an enlarged spleen weighing 180 gm and measuring 9x8x6 cm was identified. On cut section, an eccentric unilocular cyst measuring 7x6 cm was identified. The cyst was filled with brownish mucoid material and thickness of cyst wall was0.1-0.2 cm. Microscopically, the cyst wall was lined by cuboidal epithelium with fibrocalcified wall. Conclusion: Primary splenic cyst is a rare diagnosis. Although the diagnosis of splenic cyst can be established by radiological means, histopathology is mandatory to determine whether the cyst is primary or secondary in origin. [ABSTRACT FROM AUTHOR]

Background and Objectives: The term "Juxtafacet cyst" refers to both synovial cysts and ganglion pseudocysts associated with the lumbar facet joint. As conservative treatment for the juxtafacet cyst has a minimal effect, complete excision through surgery is considered the first choice of treatment. In this study, we retrospectively reviewed the clinical outcomes of percutaneous epidural neuroplasty for symptomatic lumbar juxtafacet cysts. Materials and Methods: We conducted a retrospective review of 34 patients with symptomatic juxtafacet cysts who visited a single institute from January 2010 to September 2023. Patients who received conservative treatment for at least 6 weeks but experienced no or insufficient effects were eligible for this study. After neuroplasty, a medical history check and neurological examination were performed during follow-up at 2 weeks, 1 month, 2 months, 3 months, 6 months, and once a year thereafter. Results: The pain improved for all patients to a VAS score of 3 or less immediately after neuroplasty; however, four of those patients (11%) had pain that worsened eventually to the same level as before the procedure and required surgery. The results showed that, regardless of cyst size, in cases with severe stenosis of the spinal canal, the outcome of neuroplasty was poor and often eventually required surgery. The cyst size was not associated with the procedure results. In addition, if the cyst was present at the L4–L5 level, or if diabetes mellitus was present, the likelihood of future surgery was significant (p-value = 0.003). Conclusions: Percutaneous neuroplasty showed a better success rate than other non-surgical treatments. In addition, severe spinal stenosis (Schizas grade C or higher), L4–L5 level, or diabetes mellitus produced a high possibility of surgery due to recurrence. [ABSTRACT FROM AUTHOR]

Intraosseous arteriovenous malformations (AVM) are uncommon high-flow vascular malformation that can affect the maxilla or mandible. AVM may present with aspecific and misleading signs and symptoms. The diagnosis is often accidental and bleeding may represent the first symptom. Radiographically, there are few characteristic features and misdiagnosis is easy. Here we report the case of a young male affected by arteriovenous fistula on the right side of the mandible initially misdiagnosed as a cystic lesion. The patient underwent transarterial embolization of the vascular malformation and subsequently the lesion was surgically removed. 1-year follow-up showed complete healing of the mandibular bone and absence of recurrence. Intraosseous arteriovenous malformations are rare entities. However, due to their harmfulness, both clinicians and radiologists must be aware of this type of lesion and should always consider them in the differential diagnosis of osteolytic lesions.

Objective: The aim of this study was to clarify numerical values for differentiating nasopalatine duct cysts (NPDCs) from radicular cysts (RCs) arising in the anterior maxilla on computed tomography (CT) or cone-beam CT (CBCT) images. Methods: CT or CBCT images of histologically proven NPDCs (n = 30) and RCs (n = 33) beyond the midline of the maxilla were investigated to determine two asymmetry indices on axial images of the maximum lesion area. The lateral asymmetry index was calculated based on two distances from each of the lateral ends of the lesion to the midsagittal plane. The index was defined as the difference between the two distances divided by their sum. The labio-palatal asymmetry index was determined by the distance between the labial and palatal ends of the lesion and the coronal plane passing through the central incisor root apex. The performance of these indices was assessed by receiver operating characteristic (ROC) analysis. The cutoff values for differentiating NPDCs from RCs were determined with the Youden procedure on the ROC curve. Results: The area under the ROC curve was 0.97 for the lateral asymmetry index and 0.88 for the labio-palatal asymmetry index. The cutoff values for differentiation were 0.36 and 0.68 for the lateral and labio-palatal asymmetry indices, respectively. Conclusion: The lateral asymmetry index appeared to be an effective reference for differentiating NPDCs from RCs on CT or CBCT images. When the index was less than the cutoff value, a diagnosis of NPDC was strongly suggested. [ABSTRACT FROM AUTHOR]

Chlorocresol has antibacterial and antifungal properties, yet its effectiveness in eradicating Acanthamoeba spp. remains unexplored. Acanthamoeba species trophozoites are usually sensitive to biocides, whereas cysts tend to be more resistant. This study aimed to evaluate the cysticidal activity of chlorocresol against Acanthamoeba polyphaga. Chlorocresol concentrations of 0.02, 0.04, and 0.08% were prepared and A. polyphaga cysts were incubated at room temperature (28–37 C) for 1, 24, 48, and 72 hr at each concentration. Cyst viability was evaluated using trypan blue staining and the percentage of nonviable cysts was calculated. For qualification assays, treated cysts were cultured on nonnutrient agar medium coated with Escherichia coli, incubated at 30 C, observed under a stereomicroscope for 30 days, and inoculated into peptone–yeast extract–glucose medium at 30 C for 72 hr. The results revealed that the A. polyphaga cysts were susceptible to 0.02, 0.04, and 0.08% chlorocresol. Chlorocresol made a significant difference in viability (P < 0.001) compared with the nontreated control for the same incubation time. This is the first study to examine the efficacy of chlorocresol against A. polyphaga cysts and it was highly effective. Chlorocresol could thus serve as an alternative chemical disinfectant for the eradication of A. polyphaga cysts as well as a prophylactic against transmission of other pathogenic microorganisms for which Acanthamoeba species can act as a carrier.

As an economically important plant parasitic nematode (PPN), Heterodera filipjevi causes great damage on wheat, and now it was widely recorded in many countries. While multiple genomes of PPNs have been published, high-quality genome assembly and annotation on H. filipjevi have yet to be performed. This study presents a chromosome-scale genome assembly and annotation for H. filipjevi, utilizing a combination of Illumina short-read, PacBio long-read, and Hi-C sequencing technologies. The genome consists of 9 pseudo-chromosomes that contain 134.19 Mb of sequence, with a scaffold N50 length of 11.88 Mb. In total, 10,036 genes were annotated, representing 75.20% of the total predicted protein-coding genes. Our study provides the first chromosome-scale genome for H. filipjevi, which is also the inaugural high-quality genome of cereal cyst nematodes (CCNs). It provides a valuable genomic resource for further biological research and pest management of cereal cyst nematodes disease. [ABSTRACT FROM AUTHOR]

Background: Teratomas are germ cell tumors composed of somatic tissues from up to three germ layers. Primary retroperitoneal teratomas usually develop during childhood and are uncommon in adults and in the retroperitoneal space. While there are only a few cases of retroperitoneal thyroid tissue, we report a unique case of a retroperitoneal papillary thyroid carcinoma. Case presentation: A 41-year-old woman presented in our institution due to intermitted unspecific abdominal pain. Magnetic resonance imaging detected a multi-cystic solid retroperitoneal mass ventral to the psoas muscle and the left iliac artery. After surgical removal of the retroperitoneal mass, histology sections of the specimen indicated evidence of papillary thyroid carcinoma cells. A staging computed tomography scan of the body showed no further manifestations. To reduce the risk of recurrence, total thyroidectomy was performed followed by radioiodine therapy with lifelong hormone substitution. Conclusions: Primary retroperitoneal teratoma with evidence of papillary thyroid carcinoma is a rare condition. Preoperative diagnosis is difficult due to its non-specific clinical manifestation and lack of specific radiologic findings. Histopathology analysis is necessary for diagnosis. Although surgery is considered the first line treatment, there is still discussion about the extent of resection and the need for total thyroidectomy with adjuvant radioiodine therapy.

Abnormal lung development can cause congenital pulmonary cysts, the mechanisms of which remain largely unknown. Although the cystic lesions are believed to result directly from disrupted airway epithelial cell growth, the extent to which developmental defects in lung mesenchymal cells contribute to abnormal airway epithelial cell growth and subsequent cystic lesions has not been thoroughly examined. In the present study using genetic mouse models, we dissected the roles of bone morphogenetic protein (BMP) receptor 1a (Bmpr1a)-mediated BMP signaling in lung mesenchyme during prenatal lung development and discovered that abrogation of mesenchymal Bmpr1a disrupted normal lung branching morphogenesis, leading to the formation of prenatal pulmonary cystic lesions. Severe deficiency of airway smooth muscle cells and subepithelial elastin fibers were found in the cystic airways of the mesenchymal Bmpr1a knockout lungs. In addition, ectopic mesenchymal expression of BMP ligands and airway epithelial perturbation of the Sox2-Sox9 proximal-distal axis were detected in the mesenchymal Bmpr1a knockout lungs. However, deletion of Smad1/5, two major BMP signaling downstream effectors, from the lung mesenchyme did not phenocopy the cystic abnormalities observed in the mesenchymal Bmpr1a knockout lungs, suggesting that a Smad-independent mechanism contributes to prenatal pulmonary cystic lesions. These findings reveal for the first time the role of mesenchymal BMP signaling in lung development and a potential pathogenic mechanism underlying congenital pulmonary cysts. [ABSTRACT FROM AUTHOR]

Introduction: The optimal arthroscopic management for popliteal cyst decompression remains uncertain, with ongoing debate between preserving the cyst wall or completely removing it. The purpose of this study is to compare the outcomes and complications of arthroscopic popliteal cyst decompression with cyst wall preservation and cyst wall resection. Methods: A systematic review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines was conducted. It encompassed studies that focused on arthroscopic popliteal cyst decompression, considering both cyst wall preservation and cyst wall resection. The quality assessment of the included studies was carried out using the Methodology Index for Non-Randomized Research criteria. Following this, meta-analyses were conducted, employing odds ratios (ORs) for dichotomous outcomes and calculating mean differences (MDs) for continuous outcomes. Results: Four articles included a collective of 214 knees. Each of these studies presented level 3 evidence. The comparison between the cyst wall preservation group and the cyst wall resection group revealed similar clinical outcomes based on the Rauschning and Lindgren grade (grade 0 [OR = 0.66, 95% CI: 0.37–1.19, p = 0.17]; grade I [OR = 1.33, 95% CI: 0.66–2.67, p = 0.43]; grade II [OR = 1.39, 95% CI: 0.46–4.14, p = 0.56]; grade III [OR = 3.46, 95% CI: 0.13–89.95, p = 0.46]) and Lysholm score (MD = 0.83, 95% CI: -0.65–2.32, p = 0.27). However, MRI results indicated a significant improvement in the cyst wall resection group (cyst disappearance [OR = 0.50, 95% CI: 0.28–0.90, p = 0.02]; cyst shrinkage or decrease in size [OR = 1.41, 95% CI: 0.78–2.55, p = 0.26]; cyst persistence or recurrence [OR = 7.63, 95% CI: 1.29–45.08, p = 0.02]). Nevertheless, the operative time for cyst resection was significantly longer compared to cyst preservation (MD = -14.90, 95% CI: -21.96 – -7.84, p < 0.0001), and the cyst wall resection group experienced significantly higher complications than the cyst wall preservation group (OR = 0.24, 95% CI: 0.06 to 1.02, p = 0.05). Conclusion: During arthroscopic popliteal cyst decompression, cyst wall resection led to longer operative times and higher complication rates but lower recurrence rates and better MRI outcomes. The functional outcomes after surgery were found to be similar. [ABSTRACT FROM AUTHOR]

Aim: Our aim was to investigate the frequency of various splenic cysts, to define the sonographic differential diagnostic clues and to introduce the value of twinkling artefact in the diagnosis of epidermoid splenic cysts. Material and methods: All the splenic cysts imaged by ultrasound in 3 university hospitals during the period of 2005 to 2022 were recorded, followed-up and analyzed. Results: One hundred seventy-one patients with splenic cysts were detected and these were classified and 73% of the cysts were simple. Ten cysts were epidermoid cysts as proven by post-operative final histology. Conclusion: Cystic splenic lesions are rare. Most of them are small simple cysts. Epidermoid cysts are larger in volume, constitute 6% of the total and can be differentiated by the help of twinkling artefact by Doppler ultrasound. [ABSTRACT FROM AUTHOR]

Objectives: A mucous retention cyst is a common, asymptomatic lesion that may cause complications during or after the sinus lift procedure. The goal of this study is to assess the effectiveness of the Croco Eye Technique (CET), which allows simultaneous excision of the cyst and sinus floor elevation. Methods: The technique was thoroughly described in two versions, and the group of 33 patients was analyzed. Patients who qualified for this procedure had insufficient alveolar ridge height, and their CBCT showed radiological images typical for retention cysts. Analyzed parameters included the version of CET, demographic data, anatomical parameters, intraoperative complications, recurrence of the cyst, success rate of the sinus lift and implants, and the follow-up period. Results: Out of the 33 cases, 9 were of the primary version (27.27%) and 24 of the final version (72.73%). The average height of a retention cyst was 24.05 mm, with the average alveolar ridge height of 1.86 mm. In three cases (9.09%), implants were placed immediately. The prevalence of uncontrolled Schneiderian membrane perforation was reduced from 55.56% to 4.17% between the primary and final versions. The cyst's recurrence rate was 3.13%. The implant survival rate was 100%. The mean follow-up period was 48.625 months (max 110 months). Conclusions: The Croco Eye Technique, despite the perforation of the Schneiderian membrane, enables successful sinus lift and implantation with a success rate of 100%. Excision of the retention cyst, which is the cause of perforation, allows for limiting the risk of the cyst's recurrence. [ABSTRACT FROM AUTHOR]
