A 60-year-old man with epigastric distention and right shoulder pain. The axial CT scan showed a large (10.2 cm × 8.6 cm × 6.3 cm), lobulated and irregular mass in the left hepatic lobe (segment IV). a Pre-contrast CT scan: the ill-defined heterogeneous hypodense lesion (arrows). b Contrast-enhanced CT scan (arterial phase): the hypoattenuated mass with irregular margin lesion was not enhanced on the arterial phase. A dilatation of intrahepatic bile ducts (arrow). c Contrast-enhanced CT scan (portal phase): delayed vague enhancement in the portal phase, indicating intrahepatic cholangiocarcinoma (ICC). Minimal peripheral enhancement observed during the phases (arrow). d Contrast-enhanced CT scan (portal phase): a low-attenuation lesion in the left side of the portal vein (arrow). Note the mild infiltration adjacent to the tumor
