Hemangiopericytoma is a rare (up to 1%) primary intracranial neoplasm. According to the WHO classification, hemangiopericytoma belongs to tumors of unknown origin, although some consider them to be histologically similar to angioblastic meningiomas. There is a hypothesis that they come from pericytes—cells surrounding capillaries (Casentino et al. 1993; Parker et al. 1999). Macroscopically hemangiopericytomas resemble meningiomas. Mostly these are dense tumors with a lumpy surface, often well demarcated, infiltrating the brain tissue, and attached to the dura mater with their wide base and are exceptionally well vascularized (Konovalov et al. 2005).
