A Case of Inflammatory Pseudotumor of the Liver which Increased on Ultrsonography and Computed Tomography

Abstract

We report a case of inflammatory pseudotumor of the liver, for which a right extended lobectomy was performed. The patient was a 50-year-old man with epigastric pain. Endoscopy revealed a gastric ulcer and ultrasonography revealed out a tumor for the liver. Computed tomography (CT) showed a low density area in the right lobe of the liver. Contrast enhanced CTdemonstrated a mass lesion composed of the low density areas with peripheral enhancement which gave a mosaic appearance. Aspiration biopsy of the tumor was performed, and then no malignant cells were found in the specimen except for the fibrous tissue. After 22 months, a CT scan showed that the size for the hepatic mass had definitively increased. An operation was performed and pathological findings showed that the tumor was an inflammatory pseudotumor.
