Computed tomography of adrenal metastases in hepatocellular carcinoma. Report of four cases.
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.
