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.

Hemangiopericytomas were originally thought to originate from pericytes of … Unpredicted sudden death arising from hemangiopericytoma with massive intracranial hemorrhage is quite rare. We encountered a patient with recurrent infratentorial hemangiopericytoma presenting as life-threatening massive intracerebral hemorrhage. 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.

Hemangiopericytomas are considered malignant lesions (sarcomatous lesions associated with blood vessels).

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 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 types of tumors are typically slow-growing, may be either benign (non-cancerous) or malignant (cancerous), and may occur anywhere in the body.

Hemangiopericytomas are a type of rare tumor involving blood vessels and soft tissues. Hemangiopericytomas often are painless masses and may not have any associated symptoms. These hemangiopericytoma tumors can originate anywhere in the body where there are capillaries. The most common locations reported are the brain, lower extremities, pelvic

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. Hemangiopericytoma is a term formerly used to describe a continuum of mesenchymal tumors with elevated cellularity found throughout the body in soft tissue and bone. 2018-08-01 Meningeal hemangiopericytoma is a rare neoplasm arising from perivascular pericytes.

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.

If you are experiencing issues, please log out of AAN.com and clear history and cookies. Definition: A hemangiopericytoma is a tumor that arises from cells around the blood vessels in various parts of the body, including the brain.The World Health Organization classifies hemangiopericytomas that occur in the brain as grade II or III (anaplastic) depending on the aggressiveness of the tumor. Hemangiopericytoma (HPC) is an uncommon neoplasm characterized by a dense, blunt spindle-cell proliferation with a richly vascular stroma. Supporting blood vessels often assume a staghorn configuration.

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.

The tumors showed mature, differentiated, and undifferentiated cells with frequent mitoses, and an abundance of anaplastic cells. Hemangiopericytoma tumors are a rare type of tumor in the blood vessels and soft tissue of the brain.
