<p>A solitary fibrous tumor is a rare neoplasm that typically arises from the pleura, but recently, there have been reports of the tumor arising from other areas as well. A 33-year-old female patient presented to us with the chief complaint of nasal obstruction and was found to have a nasal tumor. MRI showed a low-intensity mass on T1-weighted images and a high-intensity mass on T2-weighted images. The tumor cells were immunohistochemically positive for STAT6 and CD34; especially, STAT6 has a high specificity for SFT and a positive result for this maker was useful for preoperative diagnosis. We considered resection of the tumor by the endoscopic transnasal approach under general anesthesia and evaluated the blood flow in the tumor by CT angiography. After the operation, the patient has shown no evidence of recurrence until now, 24 months since the surgery.</p>
