Meningeal hemangiopericytoma

Abstract

Meningeal hemangiopericytomas are rare malign mesenchymal tumors accounting for less than 0.4% of all intracranial tumors. They are accepted as an aggressive form of solitary fibrous tumors and classified as World Health Organization grade II or III lesions. The clinical behavior of these tumors is highly aggressive and they are prone to local recurrence and extracranial metastasis. In clinical practice, pre-operative diagnosis of meningeal hemangiopericytomas plays a key role in treatment selection and surgical planning. However, their radiological imaging features can be almost indistinguishable from those of meningiomas. Here, we aimed to present a 46-year-old male with anaplastic hemangiopericytoma and to emphasize the distinctive radiological features specific to hemangiopericytoma.
