However, late local recurrences and distant extraneural metastases ranging from 12% to 57% are reported in literature after complete removal. Hemangiopericytoma is still current terminology in the CNS and is a distinct neuropathologic entity (not lumped together with solitary fibrous tumor) Formerly called angioblastic meningioma Brain hemangiopericytoma can mimic meningiomas around the brain and skull base, causing neurologic disturbances.

Meningeal hemangiopericytoma is a rare neoplasm arising from perivascular pericytes. Accounting for < 1% of all brain tumors, these neoplasms are characterized by a high local recurrence rate and metastatic potential. Meningeal hemangiopericytoma occur most frequently during the fifth decade of life, with an almost equal sex incidence.

Conventional radiographs are rarely diagnostic of hemangiopericytoma in any region of the body. The most common finding for a primary lesion is a nonspecific soft-tissue mass; approximately 10% contain speckled calcification . Pulmonary metastases are seen as one or more well-defined nodules or masses, but the appearance is nonspecific. Soft tissue - Solitary fibrous tumor (extrapleural); fibroblastic tumor characterized by haphazardly arranged spindled to ovoid cells, prominent staghorn vasculature and NAB2-STAT6 gene rearrangement A brain aneurysm is a weak spot or bulge in a brain blood vessel. It can happen to anyone at any age, but it's more common in people over age 40. Higher rates of aneurysms are seen in women than men, according to Web MD.
