The most common symptoms were obstruction (69%) and epistaxis (35%). All tumors were localized in the nasal cavity, and half had extension to 1 or more sinuses. Resection was performed endoscopically in 6 patients. Median intraoperative blood loss was 500 mL; median operative time was 165 minutes. Two patients received postoperative radiation. There were no recurrences with a median follow\u2010up of 25 months. Three patients presented with recurrences, 2 local and 1 distant, up to 13 years after primary tumor removal.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Surgery for sinonasal hemangiopericytomas can be challenging; both endoscopic and open approaches may be used to treat these highly vascular tumors. \u00a9 2011 Wiley Periodicals, Inc.
