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. We present a case of a 30-year-old woman with low-back pain with radiation to the left buttock for 1 month. Magnetic resonance imaging (MRI) showed a tumor mass with areas of serpentine signal void pattern in the sacrum suggestive of a vascular tumor.

These tumors are derived from mesenchymal cells, can be benign or malignant, and occur more commonly in the lower extremities, but they have been described in the liver, pelvis and retroperitoneum.

ient concerns: A 62-year-old woman presented with symptoms of hypomnesia, hyperopia, and double vision for 1 month. Complete tumor excision was performed 6 years before.

The patient went on to have surgery. Histology Paraffin sections show a densely cellular, dural-based tumor. Tumor cells have pleomorphic round, oval and elongated nuclei with vesicular chromatin and a variable amount of cytoplasm and are arran Solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) have been combined into a single designation in the most recent World Health Organization (WHO) guidelines as solitary fibrous tumor/hemangiopericytoma (SFT/HPC).

Solitary fibrous tumors (SFTs) are a rare group of spindle cell neoplasms that include fibrous-to-cellular SFTs and related lesions such as lipomatous hemangiopericytoma and giant cell angiofibroma . SFTs were first described as originating from the pleura [ 2 ] and occurring most commonly in the thoracic cavity [ 3 , 4 ], but it is now recognized that these rare tumors can occur throughout
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 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.
