Intra-abdominal Cerebrospinal Fluid (CSF) pseudocysts are a well-known and potentially serious complication of Ventriculoperitoneal (VP) shunt placement. These cysts are often found within the peritoneal cavity or along the serosal surface of solid organs. Here, we present an unusual case of an intrahepatic CSF pseudocyst in a 14-year-old female patient with a VP shunt placed three years ago, following the excision of a cerebellar pilocytic astrocytoma. The child presented with complaints of right hypochondriac pain and tenderness for one month. On ultrasound of the abdomen, the right lobe of the liver showed a complex anechoic cystic collection with multiple thick internal septations. A Contrast-enhanced Computed Tomography (CECT) examination revealed a well-defined hypodense collection in segments IV and V of the liver with a VP shunt tube within. Based on clinical and imaging features, differentials of intra-axial intrahepatic CSF pseudocyst, complex hepatic cyst, peri-shunt hemorrhagic cyst, and biliary cystadenoma were considered. Aspiration of the cyst revealed clear, colourless, non purulent, non sanguineous fluid which tested positive for beta-2-transferrin, confirming the collection to be a CSF pseudocyst. An elective laparoscopic cyst excision with shunt revision was performed with no recurrence on follow-up. The present case highlights the uncommon occurrence of intrahepatic CSF pseudocysts post-VP shunt, necessitating meticulous diagnostic evaluation. Successful laparoscopic excision and shunt revision underscore the efficacy of tailored interventions. This contribution enhances the understanding of atypical complications in VP shunt recipients, guiding clinicians and radiologists in both diagnosis and management.

Aim: Surgery for pediatric choledochal cyst (CC), complete excision (CE), and Roux-en-Y hepaticojejunostomy anastomosis (HJA) can be performed using laparoscopy (Lap), robotic-assistance (Rob; da Vinci Xi/Si), or both (Lap/Rob). Methods: Lap was used exclusively between 2009 and 2021 (n = 31) and Rob was introduced in 2017 (n = 23). All subjects were matched for age, weight, BMI, and episodes of preoperative pancreatitis. For Rob, the first 15/23 were Lap-CE/Rob-HJA and the last 8/23 were Rob-CE/Rob-HJA. Results: Total anastomotic time (TAT), TAT per suture during HJA, and time taken for dissection during CE were significantly shorter with less variance for Rob, although overall operative times were similar. Serum amylase on postoperative days 3, 5, and 7 were significantly higher for Lap. Times taken to ambulate, for return of bowel sounds, and discharge home were all significantly shorter for Rob. All postoperative complications occurred after Lap; HJA leak (n = 1; 3.2%), HJA stricture (n = 1; 3.2%), both treated by open re-HJA; and pancreatic fistula (n = 6; 19%), all treated conservatively. Conclusion: Dissection and recovery were faster with Rob while overcoming Lap-associated shortcomings to prevent complications associated with suturing. Both CE and HJA were safer and more reliable with Rob, a reflection of Rob's superiority. [ABSTRACT FROM AUTHOR]

Retroperitoneal Cysts (RPC) are uncommon, with an estimated incidence of 1 in 5,750 to 1 in 250,000. A 26-year-old woman presented with dull aching, non-radiating pain in the upper abdomen for the past two months, with no aggravating or relieving factors. On clinical examination of the abdomen, a grossly visible mass measuring approximately 10x10 cm with a smooth surface, firm consistency, and well-defined borders was observed in the left lumbar and iliac region. Contrast-Enhanced Computed Tomography (CECT) of the abdomen and pelvis revealed a well-circumscribed cystic lesion measuring 9.3x9.5x5.5 cm in the left lumbar region near the tail of the pancreas. The pancreas appeared normal with no surrounding fat stranding or inflammatory changes. Peripheral enhancement and peripheral wall calcification were observed. The patient underwent laparotomy and cyst excision. Intraoperatively, the cyst was found to arise from the retroperitoneum located in the lesser sac. It was dissected out from the tail of the pancreas, and no obvious communication with the pancreas was observed. The cyst was excised completely. Histopathological examination revealed a cyst with absent endothelium, suggestive of a pseudocyst. Previous literature reports indicate that RPCs are very rare and are often discovered incidentally. Patients may be asymptomatic or present with vague symptoms. Imaging can help diagnose these lesions, but surgery is crucial in confirming the diagnosis.

Hydatid cysts can occur in any organ of the human body and the lung is the most common site in children, primarily related to higher lung tissue elasticity. Bilateral pulmonary hydatid cyst is a rare clinical phenomenon in young children. Here, we report on a 3-year-old boy diagnosed with bilateral pulmonary hydatid cyst after he came with four months history of dry cough and progressive worsening of shortness of breath. Computed tomography of the chest revealed large bilateral thick-walled pulmonary cystic mass lesions, with bilateral perihilar extension and pressure effect on the diaphragm with surrounding atelectatic changes. The patient underwent left posterolateral thoracotomy and cyst excision was done for the left hydatid cyst. Two months after the first surgical cyst excision, right posterolateral thoracotomy and cystectomy was done for the right lung hydatid cyst. He recovered well post-operatively.Keywords: hydatidosis, Echinococcus granulosus, chest tomography, cyst excision

Objective To describe an arthroscopic technique for giant meniscal cyst excision with preservation of the functional meniscus, report the short‐ and medium‐term outcomes, and assess magnetic resonance imaging (MRI) for follow‐up imaging evaluations. Methods A total of 54 consecutive patients with symptomatic meniscal cysts were admitted to the Second Xiangya Hospital of Central South University between 2014 and 2019. Nine patients with giant meniscus cysts (six females and three males) were included in this study. The age range of the patients was 6–34 years. All patients underwent a complete physical examination, X‐ray, Doppler ultrasound, and MRI of the knee preoperatively. After an arthroscopic diagnosis of a meniscal rupture with a giant meniscal cyst, partial meniscectomy, ablation of the cyst, and suturing of the retainable meniscus were performed. Lysholm and International Knee Documentation Committee (IKDC) scores were used preoperatively and at the most recent follow‐up. Clinical outcomes were classified into four categories: excellent, good, fair, and poor. During the last visit, all patients underwent MRI to assess the recurrence of the cyst and meniscal suture healing. Results Preoperative MRI and arthroscopic examination revealed giant meniscal cysts combined with meniscal tears and congenital discoid meniscus, and all giant meniscal cysts occurred in the lateral meniscus. The main types of meniscal tears were horizontal and complex tears. The cysts were unicystic in one case and multicystic in eight cases. The mean size of the cysts on the MRI was 5.86 cm × 2.24 cm × 2.48 cm. The mean follow‐up periods were 37.5 (19–60) months. Clinical outcomes were excellent in six patients and good in three patients. The postoperative scores were significantly improved compared to the preoperative scores (Lysholm: 90.78 ± 4.60 vs. 54.56 ± 7.25; IKDC: 96.2 ± 3.46 vs. 61.69 ± 3.36; p

No recurrence of the cyst was indicated on the MRI, and there was good healing of the torn meniscus. Conclusions: Arthroscopic cystectomy combined with the meniscus suture technique was effective to eradicate residual cyst cavities, and traffic orifices be highly recommended. [ABSTRACT FROM AUTHOR]

• Most series of SEAC cases were reported. • Novel key findings of pathogenesis and Clinical features. • Novel key findings of classification. • Novel key findings of treatment strategies. • Novel key findings of microsurgery. We designed this study to share our management experiences on spinal extradural arachnoid cysts (SEACs) to add more to the body of evidence for their treatment. We retrospectively reviewed 41 patients who underwent microsurgery for thoracolumbar SEACs at our hospital from June 2009 to June 2019. All clinical data, including medical history, clinical features, imaging manifestation, operative findings, and prognosis, were extracted from medical records and databases. Perioperative differences of the Visual Analogue Scale (VAS), the Oswestry disability index (ODI) score, and postoperative Odom's criteria were used to assess the surgical outcome. The most common and very first clinical symptom in the 41 patients was pain (VAS = 2.82 ± 0.89), and the mean ODI value was 61.7 ± 8.9%. Imaging revealed that the cystic lesions in the thoracolumbar spine involved an average of 2.85 segments. Of the 41 patients, 39 underwent total cyst excisions, and 36 had their dural defect repaired by one of three methods. The mean postoperative follow-up time was 52.3 months. Postoperatively, one case developed kyphoscoliosis and two cases experienced a recurrence. The majority of patients showed excellent outcomes according to Odom's criteria, the postoperative VAS (0.80 ± 1.08), and the ODI (15.4 ± 9.3%). The most common clinical symptoms of thoracolumbar SEACs included progressive discomfort and pain around the involved spinal segments. Early surgical intervention relieved the patients from their symptoms. Microsurgery was recommended to resect the complete cyst and to repair the dural defect, but resection of the complete cyst is more necessary than just repairment of the dural defect for providing promising outcomes.

Background: Proximal tibiofibular joint (PTFJ) ganglion cysts are rare; however, their optimal management remains unclear. This study aimed to systematically review the surgical treatment options with a focus on recurrence rates and complications., Methods: A systematic review of the literature was performed, searching three electronic databases, according to the PRISMA guidelines. The presentation, treatment, and outcomes of PTFJ ganglion cysts of minimum 1-year follow-up was collected. Study quality was assessed using the Modified Downs and Blacks checklist. Surgical interventions were considered ordinally from simple to more extensive as follows; cyst aspiration, cyst excision, cyst excision with an intervention to the PTFJ, either a hemi-resection or arthrodesis., Results: Twenty-two studies comprising 100 patients (101 knees) met inclusion criteria. Among all patients, pain was present in 59.7%, a lateral fullness in 71.6% and symptoms of the common peroneal nerve in 57.4%. The overall rate of recurrence after primary treatment was 28.9%. Recurrence rates for aspiration, cyst excision, PTFJ hemi-resection and PTFJ arthrodesis were 81.8%, 27.4%, 8.3% and 0%, respectively. Revision excision for recurrence failed in all cases. Outcomes beyond recurrence were poorly reported., Conclusion: Addressing the PTFJ at the time of cyst excision reduces recurrence rates, however, the morbidity from PTFJ hemi-resection and arthrodesis are poorly reported. Whilst primary excision offers resolution in most cases (73%), revision cyst excision in isolation for the treatment of recurrent cysts is an inadequate treatment option. Cyst aspiration is ineffective. Data pertaining to patient reported outcomes for all treatment types are lacking., (Copyright © 2022 Elsevier B.V. All rights reserved.)
