Vascular tumors are rarely encountered in the paranasal sinuses. When they do arise there, they can be life-threatening because of the risk of bleeding. Embolization alone and in combination with surgical resection has been the mainstay of treatment. We report the case of a prepubertal girl who experienced two recurrences of arteriovenous malformation, one in the maxillary sinus and the other in the mandible. To our knowledge, this is the first report in the literature of recurrences arising in these two locations.
