Abstract

A 36-year-old female was referred for a huge heterogenous hepatic mass found on health check-up ultrasonography. She had no significant past medical history and was asymptomatic. All laboratory test including liver function test, tumor marker was normal. A contrast-enhanced ultrasonography, computed tomography, and magnetic resonance imaging revealed a hepatic mass 8 cm in size that occupied the right posterior segment. The lesion showed arterial enhancement, portal washout and well circumscribed margin. Based on these imaging findings, it was necessary to differentiate from malignant liver disease. Liver biopsy was performed. In the biopsy specimen, the tumor was composed mostly of epithelioid myoid cells and the fat cell component was inconspicuous, and positive for human melanoma black-45, which is common finding in hepatic angiomyolipomas. The patient underwent surgical resection and in observation in out-patient clinic.
