A hemangiopericytoma is a meningeal tumor which grows from pericytes which are modified smooth muscle cells surrounding capillaries. They typically occur in adults in the fourth or fifth decade. 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.

It may be useful in the treatment of brain tumors because it can prevent formation of for patients with recurrent hemangiopericytoma or hemangioblastoma.

The tumors showed mature, differentiated, and undifferentiated cells with frequent mitoses, and an abundance of anaplastic cells. Intracranial hemangiopericytoma (HPC) is a rare tumor of central nervous system, anaplastic type (grade 3) being the rarest. HPC closely mimics meningiomas in clinical and radiological features, thus, its diagnosis and treatment is a challenge. We report a rare case of histopathologically diagnosed anaplastic HPC of frontal lobe of the brain.

OBJECTIVE Solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is a new combined entity for which a soft-tissue–type grading system, ranging from grades I to III, has been introduced in the 2016 WHO classification of tumors of the CNS. The results of the treatment of this new disease entity require evaluation. I was recently diagnosed with anaplastic hemangiopericytoma, grade III and told that it is highly aggressive and extremely rare and treatment options are based on other grade III brain tumors.

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.

Introduction. Hemangiopericytoma is a mesenchymal tumor arising from pericytes. It was firstly reported by Stout and Murray and occurs mostly in soft tissue, including brain meninges primarily.

The brain magnetic resonance imaging (MRI) demonstrated a 2.4 × 2.5 × 2.6 cm ovoid mass in the left CPA. The tumor showed intermediate-slightly increased signal intensity in T1-weighted image (T1WI) and slightly increased signal intensity in T2-weighted image (T2WI). Diffusion-weighted imaging (DWI) did not reveal areas with diffusion

A 43-year-old man who had undergone craniotomy for total resection of an infratentorial hemangiopericytoma 17 months earlier presented with morning Hemangiopericytoma; Hemangiopericytoma ICD-10-CM Alphabetical Index. The ICD-10-CM Alphabetical Index is designed to allow medical coders to look up various medical terms and connect them with the appropriate ICD codes. There are 2 terms under the parent term 'Hemangiopericytoma' in the ICD-10-CM Alphabetical Index. Conventional radiographs are rarely diagnostic of hemangiopericytoma in any region of the body.

1973-11-01 Meningeal Hemangiopericytoma of Brain: Role of Radiation Therapy. July 2013; Online Journal of Health and Allied Sciences 12(3) 12(3) Intracranial hemangiopericytoma (HPC) is a rare tumor of central nervous system, anaplastic type (grade 3) being the rarest. HPC closely mimics meningiomas in clinical and radiological features, thus, its diagnosis and treatment is a challenge. We report a rare case of histopathologically diagnosed anaplastic HPC of frontal lobe of the brain. Hemangiopericytoma (HPC) was originally so named because it was thought to arise from vascular pericytes, Hemangiopericytomas (HPCs) represent about 0.4% of primary brain tumors.
