Figure 3. Intrahepatic cholangiocarcinoma (ICC) in a 57-year-old female. Axial gadolinium-enhanced T1-weighted MR image in hepatoarterial phase (A) and portal venous phase (B) shows a hypointense large mass (arrow) with capsular retraction and also progressive central enhancement on portal venous phase. Axial T2-weighted MR image; (C) shows the tumor has heterogeneous high signal intensity. Axial Evoist-enhanced T1-weighted MR image (D) shows rim-enhancing centrally necrotic mass. Axial diffusion-weighted MR image (E) demonstrates that the tumor restricts diffusion with the heterogeneous peripheral increased signal. ADC map (F) demonstrates a low ADC value in the rim area and a heterogenous higher ADC value in the center of the lesion.
