A capillary is a small blood vessel 5-10 um in diameter. Hemangiopericytoma of the brain can be benign (non-cancerous) or malignant (cancerous). 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.

Hemangiopericytoma brain

ABSTRACT. The authors report the histological and histochemical examination of four cases of hemangiopericytoma. 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.

My husband 1978-01-15 · Hemangiopericytoma is a rare tumor belonging to the monomorpous group of vascular neoplasms.1 Its origin from pericytes first described by Zimmerman2 has been well documented by light3 and Hemangiopericytoma: These are rare, grade II or III tumors. They appear to originate in the cells surrounding the blood vessels in the meninges. They do not invade the brain, but can recur locally or even spread elsewhere in the body (bone, lung, and liver). This spread generally does not take place until late in the disease.

Hemangiopericytoma is a neoplasm believed to be derived from pericytes, contractile cells with processes that wrap around capillaries and aid in autoregulation of blood flow. 641 There are fewer than 30 reported cases of hemangiopericytoma of the kidney, and in at least half of these the tumor involved only the renal capsule or adjacent soft tissues, without renal parenchymal involvement; in

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 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.
