Arteriovenous Malformation in a Child with Extensive Involvement of the Mandible and Maxilla.

Arteriovenous malformation of both the maxilla and mandible in a pediatric patient is a very rare phenomenon that carries with it a high mortality rate. Arteriovenous malformations, sometimes known as simple vascular tumors, can be present from birth or acquired over time due to trauma, surgery, or any kind of vascular manipulation of an area of the body.
