Abstract
A echogenic mass of 8 mm in diameter was detected by ultrasound in the liver of a 26-year-old man with normal liver function tests. Ten months later, it has grown by 2 cm. Angiography did not demonstrate a spoke-wheel pattern but faint staining of the tumor was seen. Plain CT and CT with bolus injection disclosed a low-density area that was not enhanced. With angio-CT, it was enhanced as a high-density area containing small low-density nodules. The resected specimen revieled a yellowish solid mass without fibrous capsule. Histological diagnosis was hepatocellular adenoma (HCA). Contraceptives and other drugs were not administered in this patient. The doubling time of this tumor was 96 days. HCA is demonstrated as a low-density area by CT, but angio-CT revealed it as a hypervascular tumor. These facts have not been reported and may contribute to the clinical diagnosis of HCA.
