Introduction: Hemangiopericytoma is a rare vascular tumor, which represents less than 1% of all vascular tumors. However, a relevant number of these tumors are found in the head and neck area. Objective: To describe a case of hemangiopericytoma in the sphenoid sinus. Case report: An adult female patient with nasal obstruction, presenting a tumor in the left nasal cavity, underwent complementary diagnostics tests and endoscopic endonasal surgery for complete excision of the tumor. The final diagnosis was obtained by hysthopathologic analysis. Conclusion: Few complementary tests are useful to obtain diagnosis of this hemangiopericytoma before the surgery. Routine histhopathological analysis of nasal lesions has great value.
