Juvenile nasopharyngeal angiofibroma (JNA) is an uncommon neoplasm originating between the posterosuperior and the sphenopalatine foramena in the region of the pterygoid canal [1].Although pathologically benign,JNA has a propensity for local invasion of the nasal cavity,paranasal sinus,pterygopalatine fossa,infratemporal fossa,the orbit,and even the base of the skull [2].Histologically,JNA is characterized as a non-encapsulated tumor composed of proliferating and irregular vascular component within fibrous stroma [3].
