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.

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.

Hemangiopericytoma located in the cerebral cavity is an aggressive tumor of the mesenchyme with oval nuclei with scant cytoplasm. "There is dense intercellular reticulin staining. Tumor cells can be fibroblastic, myxoid, or pericytic. These tumors, in contrast to meningiomas, do not stain with epithelial membrane antigen.

2014-07-24 · Our brain tumor journey began in 2006, when my husband Dave first began experiencing double vision. We didn't know it at the time, but we later discovered it was a symptom of hemangiopericytoma, a rare tumor that involves the blood vessels. Dave's was located in his brain.

Brain tumor manifesting as intracranial hemor- rhage is a well-known phenomenon.20) However, hemangiopericytoma is rarely associated with hemorrhage 28 Mar 2020 Hemangiopericytoma (HPC) is a rare vascular tumor that was first described A surgical plan was determined and in January 2019, a cerebral MR imaging of the brain showed a 1.5-cm diameter parasellar mass involving the sphenoid sinus, clivus, cavernous sinus, and petrous apex (Fig. 1A).

A capillary is a small blood vessel 5-10 um in diameter. 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.

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.

After discovering the underlying cause, several treatments like brain surgery and radiation were incorporated in 2007. But in 2010, Hemangiopericytoma tumor recurred.

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.
