A 21-year-old woman seen for appetite loss and diagnosed with obstructive jaundice caused by a cystic liver tumor underwent endoscopic bile duct drainage elsewhere. Cholangiography showed a smooth oval defect in the common hepatic duct. Abdominal CT and MRI showed a cystic lesion with the septum in the left medial liver segment with the cystic lesion developing into the common hepatic duct. Based on a diagnosis of intrahepatic bile duct cystadenoma, left hepatectomy was conducted. The resected specimen showed a cystic lesion in the left medial hepatic segment and a small cystic lesion developing into the common hepatic duct. Ovarian-like stroma cells were seen in the H.E.-stained specimen and she was diagnosed as having intrahepatic bile duct cystadenoma. She has had no clinical recurrence eight months after operation. No report has, to our knowledge, been made of a cystadenoma developing into the bile duct and showing a defect in common hepatic duct with cholangiography.
