Contrast CT scan showing a diffuse tumor and portal vein thrombus in a 44-year-old man. During the arterial phase, the thrombus appears as a hypodense intraluminal area with mild enhancement at the LV (white arrows, A) and PV (white arrows, C). PET/CT fused images reveal a highly metabolic mass and a highly metabolic thrombus at the LV and PV, respectively (white arrows, B, D).
