Abstract
We report a 68-year-old man with three nodules of hepatocellular carcinoma (HCC) in a cirrhotic liver; the largest nodule was 3.0 cm in diameter. The nodules showed hypoattenuation on computed tomography (CT) hepatic arteriog raphy (CTA) and hyperattenuation on CT during arterial portography (CTAP), indicating that the dominant vascularity of the HCC nodules may have been t he portal vein. A biopsy specimen obtained from the nodules showed well dif ferentiated HCC (Edmondson-Steiner grade I). The imaging findings of the no dules on both CTA and CTAP are unusual, in spite of the rather large size, so this seemed suggestive of the hemodynamic properties of relatively large nodules of well differentiated HCC.
