Figure 1. ICC in a 76-year-old female. Axial CT in the hepatic arterial phase (A) shows hypoattenuating and peripherally enhancing mass (arrow) involving nearly the entire left lobe of the liver, segment IV, and portions of segment VIII. Axial gadolinium-enhanced T1-weighted MR image in portal venous phase; (B) shows the tumor as a large multilobulated mass in the left hepatic lobe demonstrating continuous nodular peripheral enhancement with delayed fill-in. There is mild intrahepatic biliary dilatation peripheral to the mass in the left hepatic lobe. Axial maximum-intensity-projection image of ¹⁸F-FDG PET; (C) demonstrates a large left liver lobe lesion with peripheral hypermetabolic activity.
