Hemangiopericytoma (HP) is one of the meningeal mesenchymal tumors of the central nervous system in the World Health Organization (WHO) classification of tumors in 2007. In the central nervous system meningeal HP and solitary fibrous tumor (SFT) are classified as seperate tumors, while they are considered to be the same entity in the soft tissues. HP with meningeal origin are rare tumors that clinically and radiologically similar to meningioma. Because of the potential for recurrence and metastasis, these tumors are unique and their anaplastic form behave like an high-grade sarcomas. Here we present a 41-year-old male patient who admitted to our hospital with headache. Radiologically intracranial mass consistent with meningioma in the left frontal region is identified. After excision and histopathologic examination, mass was diagnosed as anaplastic hemangiopericytoma. Histopathological and immunohistochemical features of these rare tumors are discussed.
