A 62-year-old man attended another hospital for abdominal pain, where dilatation of the intrahepatic bile duct in the left hepatic lobe was discovered, in which a tumor was detected. He came to our hospital for further examination in July 2003. Abdominal CT and cholangiography revealed an intrahepatic bile duct tumor of the left lobe, which extended to the confluence of the right and left hepatic ducts. We diagnosed it as an intrahepatic cholangiocarcinoma of the intraductal growth type, and left lobectomy of the liver was deemed necessary for curative resection. Despite the poor indocyanine green clearance test (R₁₅ 37%, K 0.089), the curative resection seemed to be possible because the estimated volume of the future resected liver was small as assessed by CT volumetry. We performed left hepatic lobectomy, caudate lobectomy and extrahepatic bile duct resection in August 2003. The patient was discharged on the 23rd postoperative day without any complication. The intrahepatic cholangiocarcinoma in chronic viral liver disease has gained more attention recently, but many of which are of the mass-forming type. There has been no reported case of intrahepatic cholangiocarcinoma of the intraductal growth type in a patient with liver cirrhosis type C.
