ABSTRACT

Introduction: Hemangiopericytomas (HPC), vascular tumors, are probably originated of contractile smooth cells modified of the muscle in the external surface of posthair capillaries and venulas. Hemangiopericitomas sinonasales (SNHPC) behaves less aggressively than the HPC that happen in other regions of the body.
Material and methods: Seven proven cases of sinonasal HPC are reviewed, studied through 12 years in five diverse institutions of EUA and Colombia. The group was compound of four male and three female patients, with ages average of 50 years (of between 23 to 60 years). For their study, images of computerized tomography (CT) and magnetic resonance were used (MR). The ethiology is unknown, nevertheless, has been related to trauma, treatment long term steroid, pregnancy and hypertension, but no of them has been proven.
Conclusion and discussion: One describes to the clinical projection of image and the pathological evaluations of the seven cases. Also is the surgical behavior. Most of the patients they presented epistaxis chronic and nasal obstruction. The evaluation of the projection of image with CT and SR turned out essential to determine the extension of the tumor to plan the surgery.
