Images in a 55-year-old patient show hepatitis C-related cirrhosis and a transjugular intrahepatic portosystemic shunt (dashed arrow), with an undiagnosed tumor (dashed circle) at pretransplant imaging by both readers. Left: Noncontrast-enhanced axial CT image with a treated observation (dashed circles on the left, middle, and right images) and dense lipiodol staining (arrows) in the anterior right liver. Middle: Late arterial phase CT image with no appreciable enhancement. Right: Delayed phase image with no appreciable washout. The lesion was deemed at explant pathology to have 20% necrosis.
