Maxillary sinus arteriovenous malformation: A rare clinical entity

Arteriovenous malformation (AVM) of the head and neck is rare but a life threatening benign condition. This paper reports a case of arteriovenous malformation located in the maxillary sinus, in a 16-year-old girl. Her main complaints were nasal obstruction and rhinorrhea. Computed tomography (CT) scan and magnetic resonance imaging (MRI) evoked this entity. Complete tumor removal was performed by the Degloving approach without significant bleeding. The clinical features, therapeutic approaches and the differential diagnosis are discussed.
