Background:
Biliary cystadenomas are rare cystic tumours that arise in the liver or less frequently in the extrahepatic biliary system. They are commoner in middle-aged women, their most favoured site is the right hepatic lobe.
Methods:
Case report and review of the literature.
Results:
We present only the second case of an intrahepatic cystadenoma causing luminal obstruction of the common bile duct. Clinical presentation is often non-specific and can prove to be a diagnostic challenge.
Conclusion:
Wide local excision of biliary cystadenomas is recommended, with regular radiological follow-up.
