Introduction. Hamartomas of the bile duct (von Meyenburg complex) are benign
lesions of the liver that may mimic liver metastases. Histologically, they
consist of cystic dilatations of the bile duct, encompassed by fibrous
stroma. Case report. We reported a 68-year-old male patient in who gross,
ultrasonic and MSCT appearance suggest multiple liver metastases. The
diagnosis of von Meyenburg complex was made after histopathologic examination
of liver biopsy. Conclusion. Von Meyenburg complex in an uncommon entity
which should be taken into consideration as a differential diagnosis of liver
metastases.
Abstract
Background
Extrahepatic bile duct duplication is an extremely rare congenital anomaly in which two common bile ducts exist. There are five different types of this anomaly and we present an unusual variant of duplication of an extrahepatic biliary system of type Va variety.
Case presentation
This case report describes a 63-year-old women from rural Nepal who presented with type Va of duplicated extrahepatic bile duct, with chronic calculous cholecystitis and choledocholithiasis. She was managed with cholecystectomy with hepatic ductoplasty and hepaticojejunostomy.
Conclusion
A rare case of double common bile duct (type Va) complicated by choledocholithiasis, cholangitis, and chronic cholecystitis is reported here. Rare cases are sometimes overlooked by modern diagnostic techniques. Correct diagnosis helps appropriate surgical intervention.
Background. Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare.
Case report. We present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn’t have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images.
Conclusions. Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions.
