Large intraosseous arteriovenous malformation of the maxilla - a case report with review of literature.

Overview

Large intraosseous arteriovenous malformations (AVM) of the maxilla are rare lesions, which are probably hamartomas. We report a case of an 8-year-old child who presented with exsanguinating hemorrhage after an attempted dental biopsy. The management of dental intraosseous AVMs includes transarterial embolization and direct intralesional injection of liquid acrylic (NBCA). This approach avoids mutilating surgery and its sequelae in children. We present this case for its rarity and the intralesional use of acrylic glue in its management.
