Hemangiopericytoma (HPC) is a term used to describe a group of very rare, slow growing, benign or cancerous treatment outcomes of patients with meningeal hemangiopericytoma (M-HPC), to define the apy (bone, lung, spine, adjuvant, or salvage brain) during some Meningeal Hemangiopericytoma of Brain: Role of Radiation Therapy.

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).

They are similar to meningiomas in that they are extraaxial masses, occur in similar locations (supratentorial location being most common) and have a similar appearance on imaging.

Intracranial hemangiopericytoma (HPC) is an aggressive meningothelial neoplasm. A particularly challenging aspect of management of patients with HPC is optimizing treatment for recurrence, progression, and extracranial metastasis. Object: Intracranial hemangiopericytoma (HPC) is a rare and malignant extraaxial tumor with a high proclivity toward recurrence and metastasis.

Pathological examination of the tumor yielded findings consistent with hemangiopericytoma. Post-operatively, the patient was treated to prevent vasospasm. CONCLUSION: Although an intracranial tumor including hemangiopericytoma uncommonly causes subarachnoid hemorrhage, it should be taken into consideration as a source of intracranial hemorrhage. 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. 3 The average age at first presentation ranges from 35 to 44 years, 2,4 with patient ages from 2 days 5 to 86 years. 6 Hemangiopericytomas occurring in infants have a better prognosis than those in adults. 3 It has been recommended that treatment consist of aggressive surgical resection followed by high-dose (50 Gy) external radiation therapy and long-term 2013-11-19 · Hemangiopericytoma is a term used to described a group of tumors that are derived from pericytes, the cells normally arranged along specific types of blood vessels called capillaries and venules.

These tumors, in contrast to meningiomas, do not stain with epithelial membrane antigen.

2014-07-24 Hemangiopericytoma and Solitary Fibrous Tumors Updated by Boris Hristov BACKGROUND Are hemangiopericytomas benign or malignant lesions? Hemangiopericytomas are considered malignant lesions (sarcomatous lesions associated with blood vessels). What is the cell of origin of hemangiopericytomas? Hemangiopericytomas were originally thought to originate from pericytes of … intracranial hemangiopericytoma are similarly limited. Guthrie et al (7) described the T1-weightedandT2-weightedMRimagingfeatures in three of 44 intracranial hemangiopericyto-mas as isointense on both sequences.
