title: [Juvenile angiofibroma originating from the sphenoid sinus: a case report].
abstract: Angiofibromas are histologically benign, but unencapsulated and highly vascular tumors with a potential of local destructive effect. Angiofibromas predominantly originate from the posterolateral wall of the nasopharynx. Extranasopharyngeal angiofibromas are extremely rare and mostly seen in maxillary sinus and ethmoid sinus. In this article, we report a 21-year-old male case who was admitted with headache and diagnosed with an angiofibroma originating from the sphenoid sinus.
