색전술 후 내시경적 절제술을 시행한 비강 내 혈관근육지방종 1예

Angiomyolipomas (AML) are generally known as benign tumors. The kidney is the most common location of this tumor, and the liver is reported as the second most common site. Occurrence in other tissues is extremely rare. For instance, some cases of AML originating from the nasal cavity have been previously reported. We describe an AML case arising from the nasal cavity of a 56-year-old man. The patient had been complaining of nasal obstruction and foreign body sensation in the nasopharynx and was initially treated with preoperative angio-embolization. AML was then totally removed by endoscopic surgery without complications. He has been asymptomatic and has had no evidence of recurrence for 2 months after surgery.ope
