Rapidly aggravated skeletal muscle metastases from an intrahepatic cholangiocarcinoma

Figure 1 Computed tomography, magnetic resonance cholangiopancreatography, and positron-emission tomography-computed tomography showing an intrahepatic cholangiocalcinoma in the liver at first diagnosis. A: Computed tomography axial scan shows an ill-defined, low-attenuation mass in segments S1 and S5 of the liver; B: Contrast-enhanced, T1-weighted, axial image shows the 6-cm, peripherally enhanced mass in segments S1, S5, and S8; C and D: In the positron-emission tomography-computed tomography images, an area of strong hypermetabolism is noted (arrows), corresponding to the 6-cm soft tissue mass in the liver (maximum standardized uptake value, 10.4).
