Five out of 17.951 persons who underwent a medical check-up at our hospital were found to have mass-forming intrahepatic cholangiocarcinoma by ultrasonography (US)(detection: 0.03%). Of them, four underwent partial hepatectomy, and three are still under observation with no signs of recurrence (7 to 9 years after check-up). US proved useful in the early detection of intrahepatic cholangiocarcinoma. The US images were virtually identical in the three cases with no recurrence. But in some cases, the US images showed an atypical 15-mm hyperechoic hepatic hemangioma and in others the fatty liver presented spreading of a focal lesion. Therefore, it is important to perform examinations while always keeping in mind the existence of atypical US images.
