title: [Mediastinal hemangiopericytoma. Apropos of a case].
abstract: The authors report a new case of hemangiopericytoma in an elderly man. An asymptomatic mediastinal mass was found on a routine chest film. C.T. guided fine-needle biopsy was diagnostic. These rare lesions are clinically and radiologically aspecific and require pathologic proof. The value of percutaneous biopsy before therapeutic decision is emphasized.
