title: Intrahepatic cholangiocarcinoma associated with central calcification and arterio-portal shunt.
abstract: Although several diagnostic imaging modalities have been significantly improved in the recent years, the definitive diagnosis of intrahepatic cholangiocarcinoma (IHC) is still sometimes difficult because of the versatile features of IHC with each imaging. A 68-year-old Japanese man with alcoholic liver cirrhosis developed an intrahepatic tumor. Several imaging modalities demonstrated various features, such as central calcification and arterio-portal (A-P) shunt. Since we could not reach a final diagnosis and the tumor size gradually increased, partial hepatectomy was done after obtaining written informed consent from the patient. The postoperative histopathological examination revealed a cholangiocarcinoma. Herein, we report this case of IHC that was very difficult to diagnose due to the simultaneous association with central calcification and A-P shunt.
