title: Primary mediastinal hemangiopericytoma treated with preoperative embolization and surgery.
abstract: Hemangiopericytomas are rare tumors originating from vascular pericytes. The mediastinum is an extremely uncommon site with only a few cases reported. Diagnosis is based on histopathology and immunohistochemistry, which differentiates them from synovial sarcoma and solitary fibrous histiocytoma. They have a variable malignant potential. Treatment is mainly surgical extirpation as the role of adjuvant therapy is controversial. Preoperative embolization has been sparingly used. We report a case of primary mediastinal hemangiopericytoma in a 47-year-old man treated successfully with preoperative embolization and surgery.
