Hemangioblastomas are most often found in the lowest part of the brain, the posterior fossa (brain stem and cerebellum). However, they can also occur in the cerebral hemispheres, the spinal cord, or even the retina. Hemangiopericytomas arise in the meninges, or coverings of the brain and spinal cord. Hemangiopericytoma is a mesenchymal tumor arising from pericytes. It was firstly reported by Stout and Murray [ 1 ] and occurs mostly in soft tissue, including brain meninges primarily.

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. Hemangiopericytoma is a rare tumor with an incidence of less than 1% of all CNS tumors, 2 with only 10% of cases occurring in children.

Object: Intracranial hemangiopericytoma (HPC) is a rare and malignant extraaxial tumor with a high proclivity toward recurrence and metastasis. Given this lesion's rarity, little information exists on prognostic factors influencing mortality rates following treatment with surgery or radiation or both. A systematic review of the published literature was performed to ascertain predictors of death following treatment for intracranial HPC. Background: Hemangiopericytoma (HPC), or solitary fibrous tumor of the central nervous system (CNS), is a rare mesenchymal tumor that arises from the pericytes of the meningeal capillaries. These tumors account for less than 1% of all CNS tumors and are categorized into low-grade (WHO grade I and II) or high-grade (WHO grade III, anaplastic) neoplasms. Hemangiopericytoma is a mesenchymal tumor arising from pericytes. It was firstly reported by Stout and Murray [ 1 ] and occurs mostly in soft tissue, including brain meninges primarily. In the 2007 WHO Classification of Tumors of the Central Nervous System, meningeal hemangipericytoma is a rare neoplasm and constitutes about 0.4% of CNS tumors [ 2 Hemangioblastomas are most often found in the lowest part of the brain, the posterior fossa (brain stem and cerebellum).
