Maturity-onset diabetes of the young (MODY; OMIM # 606391) comprises a cluster of inherited disorders within non-autoimmune diabetes mellitus (DM), typically emerging during adolescence or young adulthood. We report a novel in-frame deletion of HNF1B in a family with renal cysts and MODY, furthering our understanding of HNF1B-related phenotypes. We conducted sequential genetic testing to investigate the glucose intolerance, renal cysts, hepatic cysts, and agenesis of the dorsal pancreas observed in the proband. A comprehensive clinical exome sequencing approach using a Celemics G-Mendeliome Clinical Exome Sequencing Panel was employed. Considering the clinical manifestations observed in the proband, gene panel sequencing identified a heterozygous HNF1B variant, c.36_38delCCT/p.(Leu13del) (reference transcript ID: NM_000458.4), as the most likely cause of MODY in the proband. The patient's clinical presentation was consistent with MODY caused by the HNF1B variant, showing signs of glucose intolerance, renal cysts, hepatic cysts, and agenesis of the dorsal pancreas. Sanger sequencing confirmed the same HNF1B variant and established the paternally inherited autosomal dominant status of the heterozygous variant in the patient, as well as in his father and sister. The presence of early-onset diabetes, renal cysts, a family history of the condition, and nephropathy appearing before or after the diagnosis of diabetes mellitus (DM) suggests a diagnosis of HNF1B-MODY5. Early diagnosis is crucial for preventing complications of DM, enabling family screening, providing pre-conceptional genetic counseling, and monitoring kidney function decline.

Background: The purpose of this study was to compare the efficacy of incomplete alcohol sclerotherapy with complete treatment for hepatic cysts. Methods: From 2005 to 2021, a total of 80 patients (19 males, 61 females; median age 65 years; age range, 42–86 years) who underwent alcohol sclerotherapy for symptomatic benign hepatic cysts were enrolled and retrospectively reviewed. Complete treatment was defined as injecting 25–33% of the aspirated cyst volume with alcohol in 2–3 cycles, with a maximum of 100 mL per cycle. The overall volume reduction rate was compared between the complete and incomplete treatment groups. The response, based on cystic volume reduction, was classified as a complete regression (CR), near-complete regression (NCR), partial regression (PR), or no response (NR). CR and NCR were considered objective responses. Among 80 patients with 85 hepatic cysts, 26 patients with 29 hepatic cysts received incomplete treatment. Results: The overall volume reduction rate was not significantly different between the complete and incomplete treatment groups (94.39% vs. 95.47%, respectively, p = 0.623). The CR and NCR groups showed a significantly higher rate of symptom improvement than the PR and NR groups (p = 0.043). Conclusions: In conclusion, the efficacy of incomplete alcohol sclerotherapy was not inferior to that of complete treatment. [ABSTRACT FROM AUTHOR]

Background: Cystic echinococcosis (CE) is a parasitic zoonosis caused by the tapeworm Echinococcus granulosus. Over the past few years, a lot of research has been done on liver illnesses using metabolomics techniques to identify biomarkers which could identify the diseases in its early stages. The present study was done to explore biomarkers in serum, urine, and cystic fluid which would help in differentiating, staging, and assessing fertility of intra-abdominal hydatid cyst by using proton nuclear magnetic resonance (1H NMR) metabolomics. Materials and methods: In the study, 28 subjects (16 cases and 12 controls) were enrolled. Staging of hydatid cysts was performed using ultrasonography. In patients complying with case and control definition, blood, urine, and cystic fluid were collected for complete blood count, urine culture, Echinococcus IgG enzyme-linked immunosorbent assay (ELISA), and metabolomic analysis. The 17, 15, and 11 metabolites in serum, urine, and cystic fluid samples were quantified, respectively, to differentiate between case and control group. Results: In this study, we observed that there was a significant downregulation of succinate metabolite in urine samples of cases, down-regulation of five metabolites (isoleucine, valine, histidine, tyrosine and formate) and upregulation of alanine in cystic fluid of cases. Conclusion: Current study demonstrates that metabolomics can be used non-invasively for rapid diagnosis of CE. This is one of the very few studies, which used 1H NMR spectroscopy, to analyze the profile of metabolites in serum, urine, and cystic fluid in cases of CE and controls. [ABSTRACT FROM AUTHOR]

Symptomatic hepatic cysts are infrequent and their presentation with rupture leading to an hemoperitonium is even more uncommon. This case report illustrates the challenges associated with the diagnosis and management of a ruptured simple hepatic cyst. We report the case of 72-year-old female, a known case of liver cirrhosis, hypertension, diabetes mellitus, and cholelithiasis who presented to our center with features of acute abdomen and was diagnosed with the ruptured simple hepatic cyst. Deroofing and marsupialization of the cyst was performed. This case report emphasizes the significance of early recognition and a multidisciplinary approach in managing ruptured simple hepatic cysts. Heightened clinical awareness, coupled with advanced imaging techniques, is crucial for accurate diagnosis and timely intervention.

Biliary cystadenoma (also called mucinous cystic neoplasm with low-grade intraepithelial neoplasia) is a rare cystic tumor that arises from the biliary epithelium. The cause of biliary cystadenoma is still unclear. Jaundice is a rare presentation of intrahepatic biliary cystadenoma, which can lead to a diagnostic dilemma. Herein, we present a case of intrahepatic biliary cystadenoma that primarily exhibited as jaundice. A 56-year-old woman has suffered from yellow staining of her skin and sclera for more than 1 month. She had a poor appetite and mild epigastric pain. Laboratory examination showed elevated levels of total bilirubin and elevated carbohydrate antigen 19-9 (CA19-9). A contrast-enhanced computed tomography of the abdomen showed a 7.4 * 5.3-cm, oval, low-density lesion in the left liver parenchyma with a clear boundary and visible septa. The common bile duct was obviously dilated with wall thickening. Onmagnetic resonance imaging, the lesion in the liver showed a multilocular cystic, unenhanced long T2 signal. There was local thickening of the common bile duct wall with short T2-like filling defects and high signal intensity on diffusion-weighted imaging (DWI). The patient had no history of other malignant tumors and adjuvant therapy such as radiotherapy and chemotherapy. She was clinically suspected of having either biliary cystadenoma or a malignancy; hence, resection was performed. Macroscopically, the excised tissue specimen showed a polypoidmass in the common bile duct, which extended along the bile duct to the intrahepatic bile duct. There was a cystic and solid mass in the left liver with yellow turbid fluid, which was associated with the polypoidmass in the common bile duct. Histopathology suggests mucinous cystadenoma of the liver and hilar bile duct. The differential diagnosis of biliary cystadenoma and treatment selection have been discussed. [ABSTRACT FROM AUTHOR]

Introduction: Pseudoprune-belly syndrome is a rare anomaly, an incomplete form of Prune-belly syndrome. The etiology is not clear, and though this syndrome may present associated with other malformations, the association with a liver cyst is extremely rare. Case presentation: We report the case of a male newborn who was referred to our hospital with an antenatal ultrasound that suggested a gastric duplication. Clinical examination revealed lax abdominal wall, unilateral undescended testis and a palpable mass on the right upper quadrant with fuzzy boundaries. On laparotomy we found a giant hepatic cyst displacing the bowel to the left. The baby underwent a partial ressection and marsupialization of the cyst as total resection was infeasible. The patient's recovery was uneventful. Conclusion: Although rarely, the Pseudoprune-belly syndrome can present with a liver cyst. Large liver cysts should be partially or totally ressected as soon as possible.

Background: Simple hepatic cysts are commonly detected in the general population, both solitary and associated with Adult Dominant Polycystic Kidney Disease (ADPKD). Laparoscopic fenestration is a surgical option adopted as first-line treatment and to treat complications. The techniques reported in the literature are associated with cyst recurrence in up to 41% of cases. Methods: From 2012 to May 2021, 19 symptomatic patients diagnosed with simple HCs underwent an innovative technique for laparoscopic fenestration, which includes simultaneous ethanol injection into the residual cavity. The median follow up was 57 (range 4-116) months. We retrospectively analysed symptomatic relief obtained in the short and long term as primary outcome. We also evaluated the postoperative outcome, recurrence and re-intervention rates. Results: 11 patients (of 19) were female (58 %), with a median age of 58 (range 31-78) years. Most patients (17 of 19) experienced relief of symptoms after intervention (89,5 %). Radiological recurrence occurred in 21% of patients; nevertheless, only one patient, affected by ADPKD, experienced clinical relapse with abdominal discomfort. No patient needed reintervention. There was no major morbidity (Clavien-Dindo III-IV) nor 90-day mortality. The technique allowed early removal of abdominal drainage (median 2.5 days). Conclusions: Laparoscopic fenestration of a simple hepatic cyst, with simultaneous ethanol injection, combines the advantages of the laparoscopic approach with those of injecting sclerosing agent. The described technique is associated with symptomatic relief and a favourable outcome in the postoperative period, as well as with good long term results.

This case report will discuss a 6-month-old female, born at 37 weeks gestation, who underwent a diagnostic laparoscopy for an intra-abdominal cystic mass that was diagnosed in utero at 22 weeks’ gestation. She underwent an abdominal U/S on her second day of life. This redemonstrated the intra-abdominal cystic lesion, measuring 2.8 × 2.3 × 2.9 cm with differential diagnosis including a mesenteric cyst, enteric duplication cyst, and lymphatic malformation. The patient was taken to the operating room for surgical intervention. She was found to have a hepatic lesion, which appeared to be a simple hepatic cyst. Pathology reported this to be a benign congenital biliary-type cyst. We describe a laparoscopic approach to this benign appearing hepatic/biliary mass.

A 14-year-old spayed female Shih-Tzu was referred to the Veterinary Medical Teaching Hospital of Konkuk University for evaluation of an abdominal mass. In diagnostic imaging, two large cystic masses were identified. The affected liver lobes were surgically resected, and the specimens were submitted for histopathological evaluation and immunohistochemical staining. The two cystic lesions were diagnosed as biliary cystadenocarcinoma (BCAC). Recurrence and regional invasion were identified on ultrasonography 36 days postoperatively. The patient died on postoperative day 271. To the best of our knowledge, previously reported case studies of BCAC in dogs presented limited clinical information. In this report, we present a detailed picture comprising a range of clinical information and histopathological examination of BCAC in a dog. [ABSTRACT FROM AUTHOR]

Simple hepatic cysts, common benign liver conditions, are increasingly detected incidentally due to advancements in imaging technologies. While typically asymptomatic, complications such as compression of neighboring structures can arise, presenting unique diagnostic and management challenges. We present a doubly complicated case of a massive non-parasitic liver cyst in a 61-year-old female patient, manifesting with dyspnea and compression of the inferior vena cava. A 61-year-old female with a history of treated hypertension presented with worsening dyspnea over six months. Physical examination revealed a large, painless abdominal mass, and imaging confirmed a 20 cm cystic liver mass compressing the inferior vena cava and exerting a mass effect on the diaphragm. Surgical exploration and deroofing of the cyst led to successful resolution. The presentation of dyspnea in non-parasitic liver cysts is rare but notable, highlighting the importance of considering hepatic etiologies in respiratory symptoms. Imaging modalities such as ultrasound and CT play crucial roles in diagnosis, while MRI aids in ruling out biliary-cystic fistulas. Surgical management, particularly subcostal laparotomy, remains a viable option for complex cases. This case underscores the need for heightened awareness of atypical presentations of non-parasitic liver cysts and the significance of imaging in diagnosis. Subcostal laparotomy, though associated with limitations, remains valuable in select cases. Further research comparing surgical approaches is warranted to optimize management strategies for symptomatic non-parasitic liver cysts. • This presentation details a rare case of a massive non-parasitic liver cyst, complicated by dyspnea and compression of the inferior vena cava. • Imaging modalities including CT scans and biliary MRI were crucial in diagnosis, revealing compression not only of adjacent structures such as the inferior vena cava and the ipsilateral kidney but also demonstrating displacement of the liver against the diaphragmatic dome. • Successful resolution achieved through cyst deroofing, emphasizing the doubly complicated nature of the case. • This case highlights the atypical presentation and complications associated with hepatic cysts, emphasizing the importance of considering hepatic etiologies in such cases and the crucial role of imaging in guiding management strategies.

Background The ventriculoperitoneal shunt (VPS) procedure is still the most used technique for management of hydrocephalus. This article reports a case of hepatic cerebrospinal fluid (CSF) pseudocyst as a rare, but important, complication of the VPS insertion. Case Description An 18-year-old male presented to the hospital complaining of temporal headache and visual turbidity for approximately 3 months with a history of VPS insertion for treatment of hydrocephalus and revision of the valve in adolescence. The diagnosis was based on abdominal imaging, demonstrating an extra-axial hepatic CSF pseudocyst free from infection. Following the diagnosis, the management of the case consisted in the removal and repositioning of the catheter on the opposite site of the peritoneum. Conclusion The hepatic CSF pseudocyst is an infrequent complication of VPS procedure, but it needs to be considered when performing the first evaluation of the patient. Several techniques are considered efficient for the management of this condition, the choice must be made based on the variables of each individual case.

Introduction: Intracystic haemorrhage is a rare complication of hepatic cysts, and is often mistaken for a malignant lesion. Case Report: A 55-year-old female with a history of polycystic kidney and liver disease presented with a six-month history of abdominal distension, abdominal pain, early satiety, shortness of breath and 5 kg of weight loss. Imaging revealed a 20 cm mixed solid-cystic hepatic lesion containing peripheral avascular mobile echogenic material with a flame-like morphology. After experiencing symptomatic relief from ultrasound-guided aspiration, the patient underwent cyst fenestration for more definitive treatment. Discussion: Haemorrhagic hepatic cysts are uncommon and may present on imaging as having lace-like retractile clot, internal layering or shading of separating blood products or avascular mobile flame-like excrescences. The presence of avascular mobile flame-like excrescences appears to be a unique feature of haemorrhagic hepatic cysts. Conclusion: While haemorrhagic hepatic cysts are rare and commonly mistaken for biliary cystadenomas or adenocarcinomas, the identification of particular features on high-resolution magnetic resonance imaging and contrast-enhanced ultrasound can lead to the correct diagnosis.

Introduction: Congenital hepatic cyst is a rare hepatobiliary malformation that can present as an asymptomatic, unilocular, upper abdominal cystic mass in the fetus. Cases: We report two cases of congenital hepatic cyst in which the diagnosis was made by prenatal ultrasound at 25 and 33 weeks' gestation. The diagnosis was confirmed postnatally by abdominal ultrasound and radiologic imaging studies. Although the infants remained asymptomatic, laparoscopic excision was performed due to the increasing size of the cyst in both cases. Pathological examination of the resected specimens confirmed a simple cyst in one case and an epidermoid cyst in the other. Conclusions: Our cases and those described in the literature demonstrate the usefulness of incidental prenatal detection of congenital hepatic cyst, especially during late pregnancy. Such a diagnosis can allow for proper perinatal surveillance, selection of the route of delivery, and timely postnatal surgical intervention if required. [ABSTRACT FROM AUTHOR]

Adrenal myelolipomas are nonfunctional tumors that are usually asymptomatic; however, they have been known to coexist with other endocrine disorders, such as Cushing's syndrome, congenital adrenal hyperplasia (CAH), Conn's syndrome, and pheochromocytoma. We report a case of a 49-year-old man with hypertension and diabetes mellitus who complained of chronic abdominal pain, vomiting, and early satiety. Preoperative contrast-enhanced computerized tomography (CECT) was performed, and adrenal myelolipoma was considered, lab investigations revealed a nonfunctional tumor. CECT also revealed bilateral renal cortical cyst, right renal calculi, and hepatic cyst. A left open cortical sparing adrenalectomy was performed, pathological examination confirmed the diagnosis, and a radiological surveillance was planned for the right tumor. Four years following this, the patient came back with a similar presentation. Right adrenalectomy was performed after preoperative workup, and subsequently steroid replacement therapy was initiated. We suggest adequate follow-up of a patient presenting with adrenal myelolipoma and to explore the possibility of establishing a syndromic diagnosis such as autosomal dominant polycystic kidney disease (ADPKD).

Background: Hemorrhagic rupture of a hepatic cyst is rare. To date, very few cases have been reported in the literature. Case Report: A patient with a history of a suspected liver hydatid cyst presented to the emergency department with abdominal pain and fever. She was admitted with the presumptive diagnosis of acute cholecystitis. During hospitalization, the patient presented with hemodynamic instability and abrupt worsening of the abdominal pain. The abdominal angio-chemotherapy scan showed an abundant free peritoneal effusion and an apparent effacement of the anterior wall of a hepatic cyst of 16 cm. The patient underwent an exploratory laparotomy, deroofing of the cyst, and peritoneal lavage. The anatomopathological results showed a simple hepatic cyst. Discussion: Hemorrhagic rupture of simple hepatic cysts is a life-threatening complication and, although rare, should be included in the differential diagnosis of sudden abdominal pain in patients with a history of simple hepatic cysts.

Abstract Backgroud Hepatic cysts are the most frequent, innocuous, space-occupying lesions of the liver. The majority of solitary liver cysts are nonsymptomatic. When liver cysts reach a large size, there are some complications, including infection, rupture, spontaneous hemorrhage, obstructive jaundice, and neoplastic degeneration. Percutaneous aspiration, fenestration, hepatic resection, and liver transplantation have been proposed for symptomatic patients. Case presentation In this case report, we describe a 41-year-old woman who presented with persistent liver dysfunction, indolent xanthochromia, and skin itching for 3 months. After a series of tests, she has a 5.0 × 5.3 cm hepatic cyst with many separations in the left medial liver lobe. The obstructive jaundice was caused by a large pedunculated lump protruding into the common bile duct from the left hepatic duct. She was treated with laparotomy and this lump was completely removed from the root by choledochoscopic needle-knife electrotomy with a good clinical response. Postoperative pathology of the lump suggested a hepatic cyst wall without heterocysts or tumor cells. Conclusion Hepatic cyst wall protruding into the common bile duct can form capsular lump and result in indolent jaundice. Choledochoscopic high-frequency needle-knife electrotomy could be considered as a simple, safe and effective complementary approach for benign mass on the bile duct wall.

A female patient, 59-year-old, was complaining of abdominal pain in the right hypochondrium and mesogastrium for 6 months. Ultrasonography and abdominal computed tomography were performed, both confirming a large hepatic cyst (10.6 cm × 7.6 cm × 7.3 cm) on the left lobe. A hybrid minilaparoscopic resection was proposed. We opted for unroofing the cyst, and the procedure was uneventfully performed, with a total surgical time of 60 min. In the post-operative the patient did well, with minimal abdominal pain, being discharged on the 5th post-operative day, after drain removal due to the use of intravenous antibiotic therapy.

Context: Cysts arising from the hepatobiliary tree are a group of heterogeneous lesions with regard to pathogenesis, clinical presentation, and radiological finding. They can be intrahepatic or extrahepatic, developmental, secondary to infective/inflammatory etiologies, as well as neoplastic. This study was conducted to determine the spectrum of hepatobiliary cysts in surgically intervened cases, with regard to their prevalence, histological spectrum, and clinicoradiological correlation, wherever possible. Methods: In this retrospective observational study, hematoxylin and eosin stained slides of all cases of hepatobiliary cystic lesions, operated between 2009 and 2016 were reviewed. Special stains as reticulin, Masson's trichrome, and periodic acid Schiff were done wherever necessary. Overall prevalence, age-sex distribution, clinical presentation and histopathological patterns were studied. Relevant imaging findings were correlated wherever possible. Results: A total of 312 cases of hepatobiliary cysts were identified, the majority in females. Choledochal cysts (CCs) were the most common type (n = 198,63.5%), followed by hydatid cysts (n = 73,23.3%), simple hepatic cysts (n = 10,3.2%), congenital hepatic fibrosis (n = 10,3.2%), biliary cystadenomas (n = 4,1.2%) hepatic mesenchymal hamartomas (n = 7,2.2%), and cavernous hemangiomas (n = 3,0.9%). Fibropolycystic liver disease (n = 2,0.6%), Caroli's disease (n = 1, 0.3%), liver abscess (n = 2, 0.6%), infantile hemangioendothelioma (n = 1,0.3%), and biliary cystadenocarcinomas (n = 1,0.3%) were rare. Lesions noted mostly in 1st decade of life were: CCs, fibrocystic liver disease, Caroli's syndrome, cystic mesenchymal hamartoma, and infantile hemangioendotheliomas. Conclusion: In our cohort of surgically intervened cases of hepatobiliary cystic lesions from a tertiary care hospital in North India, the CCs, followed by hydatid cyst were the most common lesions. Histology can play vital role in characterization, as often clinical findings and radiology can overlap.

Background: Some hydatid cysts of cystic echinococcosis type 1 (CE1) lack well-defined cyst walls or distinctive endocysts, making them difficult to differentiate from simple hepatic cysts., Aim: To investigate the diagnostic methods for atypical hepatic CE1 and the clinical efficacy of laparoscopic surgeries., Methods: The clinical data of 93 patients who had a history of visiting endemic areas of CE and were diagnosed with cystic liver lesions for the first time at the People's Hospital of Xinjiang Uygur Autonomous Region (China) from January 2018 to September 2023 were retrospectively analyzed. Clinical diagnoses were made based on findings from serum immunoglobulin tests for echinococcosis, routine abdominal ultrasound, high-frequency ultrasound, abdominal computed tomography (CT) scan, and laparoscopy. Subsequent to the treatments, these patients underwent reexaminations at the outpatient clinic until October 2023. The evaluations included the diagnostic precision of diverse examinations, the efficacy of surgical approaches, and the incidence of CE recurrence., Results: All 93 patients were diagnosed with simple hepatic cysts by conventional abdominal ultrasound and abdominal CT scan. Among them, 16 patients were preoperatively diagnosed with atypical CE1, and 77 were diagnosed with simple hepatic cysts by high-frequency ultrasound. All the 16 patients preoperatively diagnosed with atypical CE1 underwent laparoscopy, of whom 14 patients were intraoperatively confirmed to have CE1, which was consistent with the postoperative pathological diagnosis, one patient was diagnosed with a mesothelial cyst of the liver, and the other was diagnosed with a hepatic cyst combined with local infection. Among the 77 patients who were preoperatively diagnosed with simple hepatic cysts, 4 received aspiration sclerotherapy of hepatic cysts, and 19 received laparoscopic fenestration. These patients were intraoperatively diagnosed with simple hepatic cysts. During the follow-up period, none of the 14 patients with CE1 experienced recurrence or implantation of hydatid scolices. One of the 77 patients was finally confirmed to have CE complicated with implantation to the right intercostal space., Conclusion: Abdominal high-frequency ultrasound can detect CE1 hydatid cysts. The laparoscopic technique serves as a more effective diagnostic and therapeutic tool for CE., Competing Interests: Conflict-of-interest statement: The authors declare that there is no conflict of interest., (©The Author(s) 2024.

Pancreatitis and pseudo-pancreatic cysts are frequently encountered entities; however, intrahepatic pseudocysts presenting as large number of liver cysts with absence of overt signs of pancreatitis has never been reported in literature. Here, we report an interesting case of multiple intrahepatic pancreatic pseudocysts (MIHPPs), a challenging diagnosis to be kept in mind while dealing with complex cystic lesions of liver. Pseudocysts are common complication of pancreatitis, often these are located within the vicinity of the pancreas in the lesser sac and the retroperitoneum. Extra pancreatic location of these cysts within the liver is a diagnosis often missed, with only 50 odd cases reported in literature till date. Most of these reported cases are either subcapsular in location or limited in number to one or two lesions. Although rare, possibility of MIHPPs is an important diagnosis that should be kept in mind while considering list of differentials for complex cystic lesions of the liver even in the absence of overt signs of pancreatitis.

Cystic hepatic lesions are commonly encountered in daily practice. The diagnosis of these lesions ranges from benign lesions of no clinical significance to malignant and potentially lethal conditions. The prevalence of hepatic cyst (HC) has been reported to be as high as 15-18% in the United States. Imaging with conventional ultrasound, computed tomography, magnetic resonance imaging, or contrast-enhanced ultrasound can be used to characterize further and diagnose. The pre-test probability of a diagnosis is highly affected by the patient's comorbidities and the clinical and laboratory data; thus, imaging studies should be interpreted in the context of the other clinical information for that particular patient. Treatment modalities for hepatic cyst include fenestration, aspiration sclerotherapy, or surgical resection. In the current review, we discuss the pathophysiology, diagnosis, and treatment modalities for various cystic hepatic lesions. [ABSTRACT FROM AUTHOR]

Echinococcosis is a zoonotic infection caused by Echinococcus granulosus, from the family of taeniidae of the cestoda class and is endemic in South America, Eastern Europe, Russia, Middle East and China1. In humans, Cystic Echinococcosis involves usually the liver and lungs. We present a rare case of a patient with extra-visceral abdominal involvement of Cystic Echinococcosis

Helicobacter cinaedi is an enterohepatic bacillus that causes infections of various manifestations. We report a novel case of hepatic cyst infection with bacteremia caused by H. cinaedi in an immunocompetent woman in Japan. Further research is warranted to identify the epidemiologic and clinical features of H. cinaedi infection.

Here, we describe the case of a 9-year-old girl. During the patient's prenatal period, her mother had suffered domestic violence perpetrated by the patient's father. On maternal ultrasonography and magnetic resonance imaging, an intraabdominal cystic lesion was detected in the fetus at around the 30th prenatal week. The patient was delivered normally, and there were no evident anomalies on her body. Computed tomography with drip infusion cholangiography and percutaneous retrograde transhepatic cholangiography demonstrated an intrahepatic cyst of approximately 3 cm in diameter, which was located at S5–S8 and communicated with the confluence of the bilateral hepatic ducts. The cyst is clinically conjectured to be a solitary intrahepatic biliary cyst. However, it remains possible that the cyst is a ciliated hepatic foregut cyst or indicates hepatic injury that may have occurred as a result of domestic violence to the mother. Careful, long-term observation of the patient will be continued to ensure that any malignant transformation is not missed.
