- Biliary cystadenoma is a relatively uncommon entity, often masking as a hepatic cyst.
- Though rare, biliary cystadenoma is thought to have malignant potential, occasionally evolving into biliary cystadenocarcinoma.
- The lesion tends to be managed only if symptomatic (surgical resection if there are complications eg rupture/bleeding)
- Radiographic feature
– Biliary cystadenoma may have internal septations or a small amount of complexity
– The greater the complexity, the higher suspicion should be raised for biliary cystadenocarcinoma transformation
- Recurrence is common after resection.
- Ddx include simple hepatic cyst, hydatid cyst and hepatic abscess.
