title: Arteriovenous malformation of the maxillary sinus: an unusual clinical presentation.
abstract: Arteriovenous (AV) malformation is a rare vascular lesion of the jaws with a benign clinical presentation. As a result, AV malformation may be excluded from a presurgical differential diagnosis, with catastrophic results. Review of the pertinent literature showed no documentation of AV malformation in the maxillary sinus, and therefore we present the case of a 43-year-old white man with a history of blunt trauma to the paranasal region, whose differential diagnosis included a vascular lesion.
