A case of intraductal growth type intrahepatic cholangiocarcinoma curatively resected 33 months after the initial diagnosis

Abstract

We experienced a case of intrahepatic cholangiocarcinoma, successfully resected 33 months after first diagnosis. A 72-year-old man, who had been referred to our hospital for the operation of intrahepatic cholangiocarcinoma and declined the treatment 2 years before, was admitted to our hospital for the same diagnosis. CT scan revealed the enlargement of the low density mass at the posterior segment of the bile duct and the atrophy of right lobe due to right portal vein occlusion. Under the diagnosis of intrahepatic cholangiocarcinoma, extended right hepatic sectionectomy and excision of the extrahepatic bile duct were performed. The lesion in the posterior segment was histologically diagnosed as intraductal growth type of intrahepatic cholangiocarcinoma, which is compatible with intraductal papillary neoplasm of the bile duct. The patient is currently alive 3 years after the operation without any signs of recurrence.
