Four patients with adrenal metastases from hepatocellular carcinoma (HCC) diagnosed with computed tomography are described. In three, the metastases showed a central area of low density due to tumor necrosis, irregular contrast enhancement, and a well-defined margin. They measured 8 cm or more in diameter. In one, the adrenal metastasis was at first a relatively small homogeneously solid mass, but later, when it grew larger, a central low density developed. Since the adrenal gland is the second most common site of metastasis from HCC at autopsy, a combination of an adrenal tumor and a liver tumor should suggest this possibility.
本文描述了4例经计算机断层扫描诊断为肝细胞癌（HCC）肾上腺转移的患者。其中3例转移灶因肿瘤坏死呈现中央低密度区，增强扫描表现为不均匀强化，边界清晰。直径均在8厘米及以上。另1例肾上腺转移灶起初为相对较小的均匀实性肿块，但后来增大时出现中央低密度区。由于肾上腺是HCC尸检中第二常见的转移部位，肾上腺肿瘤合并肝肿瘤时应考虑这种可能性。
