To improve the accuracy of diagnosis and treatment efficacy of hemangiopericytoma in nasal cavity and paranasal sinuses.
The clinical and pathological data of 5 cases with hemangiopericytoma in nasal cavity and paranasal sinuses verified by pathology were analyzed retrospectively.
Computed tomography scan revealed vascular in 5 cases. On CT scan, hemangiopericytoma generally appeared to be a uniform high density mass with obvious enhancement upon injection of contrast material. In pathological examination, there were plentiful capillaries which were like tree branch. The normal endocytes were in the inner wall of the vessel. The round, oval and spear-like pericytes scattered around the vessel. The split phase of the nucleus could be found in the tumor cell. All cases underwent surgical resection and were proved by pathological examination. The clinical data showed that the prognosis of sinonasal hemangiopericytoma was closely related to its histological grade. The recur rate in highly malignant hemangiopericy
