Abstract

We report a 68-year-old man with three nodules of hepatocellular carcinoma (HCC) in a cirrhotic liver; the largest nodule was 3.0cm in diameter. The nodules showed hypoattenuation on computed tomography (CT) hepatic arteriography (CTA) and hyperattenuation on CT during arterial portography (CTAP), indicating that the dominant vascularity of the HCC nodules may have been the portal vein. A biopsy specimen obtained from the nodules showed well differentiated HCC (Edmondson-Steiner grade I). The imaging findings of the nodules 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.

摘要

我们报告一名68岁男性，其肝硬化肝脏中有三个肝细胞癌（HCC）结节；最大的结节直径为3.0厘米。这些结节在计算机断层扫描（CT）肝动脉造影（CTA）上表现为低密度，而在动脉门静脉造影（CTAP）期间的CT上表现为高密度，这表明HCC结节的主要血供可能是门静脉。从结节获取的活检标本显示为高分化HCC（埃德蒙森-斯坦纳一级）。尽管结节尺寸相当大，但CTA和CTAP上结节的影像学表现并不常见，因此这似乎提示了高分化HCC相对较大结节的血流动力学特性。
