Multiple hepatocellular adenomas: a case report

Abstract

We report a rare case of multiple hepatocellular adenomas difficulty in ruling out well-differentiated hepatocellular carcinomas prior to resection. A 40s female was admitted to the hospital for examination of multiple liver tumors. CT and Gd-EOB-MRI showed that tumors were located in segment 2 and 5. We conducted a percutaneous tumor biopsy and tumor showed low atypical cells containing fat deposit. As the possibility of multiple hepatocellular carcinomas could not be denied, partial hepatectomy and RFA were done. All resected tumors showed a decreased expression of the liver fatty acid binding protein (L-FABP), and were finally diagnosed as multiple HNF1α-inactivated type hepatocellular adenomas. Multiple hepatocellular adenomas are rare tumors, so we report this case with review of the literatures.
