Hemangiopericytoma located in the mediastinum: a case report Mediasten yerleşimli hemanjiyoperisitoma: Olgu sunumu

Hemangiopericytomas, which arise from cells (pericytes) that are wrapped around the pericapillary arterioles, are commonly located in the soft tissue of the thigh and retroperitoneum. Hemangiopericytoma in the mediastinum is extremely rare. Fewer than 20 cases were reported and while one fourth of them was benign and the remainder was malignant. The malignant potential of hemangiopericytoma is a distinctive characteristic when compared to the other vascular tumors. A high-signal area on T2-weighted magnetic resonance imaging and a massive bleeding mass during the operation are the characteristic features of hemangiopericytoma. Complete resection is the only effective treatment option for this vascular slow-growing tumor. In this article, we report a case of a 23-year-old male who was treated by complete surgical resection of the tumor. Details of clinic, pathologic and radiographic features are presented.
