Intra-operative image showing the partially resected intrahepatic biliary cystadenoma. Partially resected left lobe with the intrahepatic biliary cystadenoma and its extension into the left hepatic duct which is cut open and the schematic diagram of the anatomical relationship of the intrahepatic biliary cystadenoma and the biliary ducts. The extrahepatic gall bladder, which is not shown in the image, was removed synchronously. (A) Intrahepatic biliary cystadenoma; (B) Polypoid extension of the intrahepatic biliary cystadenoma in the left hepatic duct (retracted upwards); (C) Opening of the left hepatic duct through which the extension of the intrahepatic biliary cystadenoma was extracted.
