Hyperdensity liver tumor on plain CT

Journal Article:

Abstract

Most liver tumors on plain CT have been recognized as low density or iso-density masses. Sometimes calcified high density masses were shown on plain CT in case of cysts or metastatic liver tumors. However, hyperdensity mass of the liver on CT, of which the density was a little higher than surrounding tissues, was very rare. Recently 7 patients with hyperdensity liver masses on plain CT were experienced: 6 hepatocellular carcinomas and 1 hepatic cavernous hemangioma. A single hyperdensity mass was shown in 4 patients, a hyperdensity mass of multiple hepatic tumors was shown in 2 patients, and some hyperdensity masses of multiple hepatic tumors were shown in 1 patient. Lesions are classified in 3 types according to the appearance of hyperdensity masses: diffuse hyperdensity all over the mass, ring like hyperdensity, creascent like hyperdensity. Intravenous contrast enhancement was performed in 2 patients: one with a primary hepatocellular carcinoma, and another with a hepatic cavernous hemangioma. In the former case the tumor margin had changed unclear, in the latter case the tumor was markedly enhanced. Our results revealed that hyperdensity liver tumors were divided into 2 types: One type, shown in a cavernous hemangioma with fatty liver, demonstrated relative hyperdensity due  More>>

Our results revealed that hyperdensity liver tumors were divided into 2 types: One type, shown in a cavernous hemangioma with fatty liver, demonstrated relative hyperdensity due to lower density of the surrounding tissue. Another type, shown in 6 hepatocellular carcinomas, showed hyperdensity since the density of the tumor was hyperdensity relative to the surrounding tissue of the liver. It was suggested that the tumor with the latter type had been strongly probable of malignant one, and been recommended to receive further examination. Cause of hyperdensity was thought to be due to hemorrhage, though microcalcification could not be denyed. In Japan, no hyperdensity liver tumor had been reported partly due to a wide window width with which CT photographs were taken.}
