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 Hemangiopericytoma is a rare type of tumor involving blood vessels and soft tissue. 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. Hemangiopericytoma (HPC) is an uncommon neoplasm arising from Zimmerman pericytes around capillaries and postcapillary venules. Most HPCs are located in the musculoskeletal system and the skin.

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.

Mean age at diagnosis is between 38 and 43 years. We present an 8-year-old boy with MHP of the middle cranial fossa. Imaging findings were indistinguishable from an aggressive bone tumor such as Ewing's sarcoma. Imaging findings are presented and discussed. Our case indicates that MHP should be considered in the differential Introduction.

One year after diagnosis, metastasis to a lumbar vertebra was discovered and additional irradiation of 3900 cGy was applied. One year later, CT showed control of the pelvic tumor Hemangiopericytoma (HPC) is an uncommon neoplasm arising from Zimmerman pericytes around capillaries and postcapillary venules.

108. Radiology Imaging May 18, 2013 - This page discusses intracranial hemangiopericytomas. Hemangiopericytoma is a neoplasm that commonly manifests as an intracranial mass lesion.[] According to the 2007 World Health Organization classification, it is a “tumour of the meninges”[] and constitutes approximately 2% of all such tumors.[8 9] Hemangiopericytoma is a clinically malignant tumor due to its high incidence of local recurrence and extraneural metastasis, which eventually Osseous hemangiopericytoma is rare.

Similar to the hemangiopericytoma of soft tissues in pathological features, first reported by Stout and Murray (), intracranial meningeal hemangiopericytoma (M-HPC) is a rare mesenchymal tumor, possibly of pericytic origin in the meninges, which was initially described by Begg and Garret () in 1954.
