title: Intrahepatic biliary cystadenoma causing luminal common bile duct obstruction.
abstract: 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.
  
  
  CONCLUSIONS
  Wide local excision of biliary cystadenomas is recommended, with regular radiological follow-up.
