==Overview==
==[[Hemangiopericytoma overview|Overview]]==


Hemangiopericytomas, along with hemangioendotheliomas and angiosarcomas are tumors that arise from vascular structures. A '''hemangiopericytoma''' ('''HPC''') is a type of [[soft tissue sarcoma]] that originates in the [[pericyte]]s in the walls of [[capillary|capillaries]] (they arise from the cells of Zimmerman, which surround vessels). Both benign and malignant forms are encountered. These tumors are most frequently seen in middle-aged adults.
==[[Hemangiopericytoma classification|Classification]]==


Typically they have large vessels especially located at its periphery, and commonly involve the lower limbs (35% of cases), especially the thigh, pelvis and retroperitoneum (25%)
==[[Hemangiopericytoma historical perspective|Historical Perspective]]==


Primary osseous lesions are rare.

==[[Hemangiopericytoma epidemiology and demographics|Epidemiology & Demographics]]==


Radiologically they appear the same as angiosarcomas and heemangioendotheliomas.

Nonspecific soft tissue mass. When involving bone, they are predominatly lytic, and may mimic hemangiomas with a course honeycomb appearance.
==[[Hemangiopericytoma causes|Causes]]==


===Angiography===
==[[Hemangiopericytoma differential diagnosis|Differentiating Hemangiopericytoma from other Diseases]]==


Dense, well-circumscribed areas of enhancement with early draining veins and shunting. Hemangiopericytoma are described as having a pedicle formed by the arteries supplying the tumor from which vessels branch to encircle the tumor.

Non specific soft tissue mass, with density similar to muscle but demonstrating bright contrast enhancement. CTA may demonstrate large feeding vessels.

Brightly enhancing soft tissue mass, often hyperintense on T2WI, with prominent flow voids, most marked in haemangiopericytomas.
