Images of a 4 cm hepatocellular carcinoma (HCC) mass in a 62-year-old woman with hepatitis B-related cirrhosis. Axial CT scans obtained during the (a) precontrast, (b) late arterial, (c) portal venous, and (d) equilibrium phases show a bulging contour mass in segment III of the liver. The tumour shows overt low attenuation in the precontrast phase, isoattenuation in the arterial phase, and relatively early washout during the portal venous phase. Pathology review of the mass lesion revealed a poorly differentiated HCC.
