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.

It was detected below the left kidney at the first US examination and had migrated into the pelvis 14 Kruse, F. Jr. Hemangiopericytoma of the meninges (angioblastic meningioma of Cushing and Eisenhardt). Clinicopathologic aspects and follow-up studies in 8 cases. Neurology, Minneap., 1961, 11: 771 – 777. Kruse, F. Jr. Hemangiopericytoma of the meninges (angioblastic 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. Intracranial Hemangiopericytoma.

One year after diagnosis, metastasis to a lumbar vertebra was discovered and additional irradiation of 3900 cGy was applied.

Hemangiopericytoma has no predilection for age or sex; it was congenital in 3 of Stout's patients. In cases of thoracic hemangiopericytoma, the age range was from ten to seventy-five years, with an average of forty-six years.

Preoperative differentiation between them is important for determining the treatment and follow-u What is the Tx paradigm for managing hemangiopericytoma? Hemangiopericytoma Tx paradigm: Complete surgical resection is the mainstay of therapy + adj or neoadj RT, chemo, or CRT. Unresectable cases can be treated with either RT alone or CRT (inferior outcome). Is there a role for chemo in the management of hemangiopericytoma? Yes. Nasopharyngeal Hemangiopericytoma Epidemiology.

They are difficult to distinguish from the far more common meningioma, but 1994-05-01 Hemangiopericytoma is an unusual vascular neoplasm that arises from the pericytes of Zimmerman. It is associated with capillaries, therefore they may occur anywhere in the body. Most common locations include the lower extremities, pelvic retroperitoneum, head and neck. Clinically, hemangiopericytoma is usually of insidious onset. The patient went on to have surgery.

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 the smooth muscle cells of vessels but are now felt to be of fibroblastic origin. Radiology Case.

Hemangiopericytoma is a rare, painless and usually asymptomatic tumor affected in soft tissues and blood vessels. Blood vessels present in all over the body and hemangiopericytoma tumors are formed anywhere in the body, because of adjacent blood capillaries.
