Abstract

A hemangiopericytoma is a rare soft tissue sarcoma that originates from pericytes. This neoplasm can occur in any part of the body but their frequent sites of origin are reported to be the lower extremities, pelvis, retroperitoneum, head, neck and trunk. A hemangiopericytoma may be curable by a surgical resection but its prognosis is poor when it recurs. Distant metastases rarely occur and the most commonly affected organs are the lung and bone. At CT, a hemangiopericytoma is typically depicted as a hypervascular tumor with a delayed fill-in of contrast enhancement from the periphery. We encountered a case of hemangiopericytoma that metastasized to the liver. We describe the radiological findings of the metastatic hemangiopericytoma of the liver.
