Hepatic adrenal rest tumor mimicking hepatocellular carcinoma

Abstract

A case of HART in a man without clinical symptoms is described. HART shows the following radiologic features: a solitary hepatic mass containing distinct components of fat and soft tissue attenuation; a round, well demarcated mass of the right posterior hepatic lobe in the subcapsular region; radiologic recognition of the original adrenal glands; blood supply of the tumor by the hepatic artery. However, if this disease itself is not in the lists of differential diagnoses, correct diagnosis is difficult only with radiologic or pathologic exams. HART should be added to the lists of radiologic differential diagnoses of hypervascular or fat-containing hepatic tumors.
