Large arteriovenous malformation of the oromaxillofacial region with multiple phleboliths

Abstract

Vascular tumors are the most common benign tumors of the head and neck in infancy and childhood. Vascular anomalies of the head and neck were divided into 2 categories including hemangiomas and vascular malformations. Oral and maxillofacial hemangiomas and vascular malformations are congenital lesions with various clinical characteristics, manifestations, indications, and possibilities for treatment. This paper reports a case of large arteriovenous malformations including a description of the features demonstrated by panoramic radiography, cone beam computed tomography, and magnetic resonance imaging. The differential diagnosis and treatment modalities (including embolization with N-butylcyanoacrylate in this case) are also discussed following the case presentation, along with the available literature review.
