Figure 4. Hepatocellular carcinoma (HCC) in a cirrhotic liver. A 75 year old man with alcoholic cirrhosis presents with worsening liver failure. The enhanced CT image (a) shows the small cirrhotic liver with cavernous transformation of the portal vein and surrounding ascites. The posterior aspect of the right lobe of the liver shows a bulbous projection suggesting a mass (white arrow). The planar (b) and transaxial SPECT (c) 99mTc-sulfur colloid images show the mass to be devoid of Kupffer cells indicating that it is not regenerating liver tissue (black arrows). A more anterior defect on 99mTc-sulfur colloid SPECT images represents scarring. 67Ga activity within the mass on planar (d) and transaxial SPECT images (e) is consistent with HCC (black arrowheads).
