Two cases of hepatocellular carcinoma (HCC) with intrahepatic bile duct tumor were reported. We didn't observe obstructive jaundice and upper abdominal pain due to the invasion to the bile duct. Imaging diagnosis by ultrasonography and X-ray computed tomography revealed the tumor growth in the bile duct in both cases and the portal vein tumor thrombus in one of them. The main tumors were less than 3cm in diameter. HCC with bile duct tumor growth often presents obstructive jaundice as icteric type hepatoma. It was considerd that a small main tumor and a localized tumor growth in the intrahepatic bile duct were the reason for having no symptoms due to the invasion to the bile duct.
