Hemangiopericytoma is a potentially malignant vascular tumor that can occur anywhere in body, the meningeal location is rare. We report the case of meningeal hemangiopericytoma in 59-year-old man. The histological approach requires the use of immunohistochemistry (CD34, Vimentin, CD31, EMA, SMA, PS100, CD99, and KI67) because this tumor is often confused with fibrous meningioma and solitary fibrous tumors. Thus, it is very important and crucial for the pathologist to identify the true nature of the tumor from the start, in order to make an appropriate prognosis. The aim of this study was to report on the clinical, radiological and histological characteristics of meningeal hemangiopericytoma. A long follow up of these patients required because of frequent recurrences and delayed metastases.
