We experienced a case of resected intrahepatic cholangiocarcinoma, which did not form a mass in the liver but was growing only in the intraductal lumen. A 62-year-old woman was admitted to our hospital for an operation for intrahepatic cholangiocarcinoma. Abdominal ultrasonography and CT revealed a 4-cm tumor, including the dilated intrahepatic duct, in the right hepatic lobe. The lobe was resected under intraoperative ultrasonography. But the resected specimen did not contain a mass and many tumor thromboses were found in the dilated hepatic duct. Histologically the bile duct wall and the tumor showed well differentiated adenocarcinoma. Clinical fiundings of the tumor growing intraductally without forming a mass are now meaning not clear. It is difficult for an intrahepatic cholangiocarcinoma with intraductal growth to be diagnosed precisely and it is necessary for us to decide on the range of resection carefully.
