Biliary cystadenoma

Case contributed by Dr Praveen Jha

Presentation

A lump in the epigastric region with some episodes of vomiting.

Patient Data

Age: 50 years
Gender: Female
Ultrasound

A large exophytic cystic lesion is seen in liver, with evidence of peripheral and septal calcifications, and moving internal echoes on ultrasound.

CT

Provisional diagnosis of Hydatid cyst and Biliary cystadenoma were considered. Histopathology revealed biliary cystadenoma

Case Discussion

Ultrasound confused me a lot, and I could not make out nature of mass. In fact, it was difficult to assess if its intrahepatic or a large epigastric cystic mass closely abutting liver like a large pseudopancreatic cyst. CT showed the intrahepatic lesion with close characteristics of biliary cystadenoma, but I preferred to give a differential of hydatid cyst. This case was operated and confirmed biliary cystadenoma on histological diagnosis.
