  		Fig. 1B. —Hypervascular hepatocellular carcinoma (HCC) in 55-year-old man with chronic hepatitis C virus infection. Portal phase CT scan obtained at same level as A shows that lesion (arrow) remains hyperenhancing. Moderate hyperenhancement of liver parenchyma in periphery of tumor is evident and consistent with transient hepatic attenuation difference.

  		Fig. 1C. —Hypervascular hepatocellular carcinoma (HCC) in 55-year-old man with chronic hepatitis C virus infection. Corresponding equilibrium phase image shows slight hypodensity of lesion (arrow) consistent with HCC.

  		Fig. 2B. —False-positive finding on helical CT in 41-year-old woman. Corresponding delayed phase CT scan shows that lesion is slightly hypoattenuating (arrow). These CT findings are highly suggestive of hepatocellular carcinoma.

  		Fig. 3A. —Understaging of hepatocellular carcinoma on helical CT in 62-year-old man. Axial CT scan in arterial phase at level of left portal vein shows two hyperenhancing lesions in segment IV and in caudate lobe (arrowheads) consistent with hepatocellular carcinoma.

  		Fig. 3B. —Understaging of hepatocellular carcinoma on helical CT in 62-year-old man. Corresponding portal phase CT scan shows that both lesions remain hyperdense relative to liver parenchyma. Lesion in caudate lobe abuts right diaphragmatic crus and obliterates focally retrohepatic fat plane (arrows). These findings were missed preoperatively. At surgery, gross extrahepatic tumor infiltration was found and complete resection was not possible.
