Traumatic arteriovenous malformation of cheek: A case report and review of literature

Arteriovenous malformations (AVM) are congenital vascular anomalies but are usually first noticed in childhood or adulthood. Head and neck is the most common location for AVM. Extracranial lesions are rare compared to intracranial lesions. The rapid enlargement of the malformation leading to symptoms is usually triggered by trauma or hormonal changes of puberty or pregnancy. Traumatic AVM of the head and neck are very rare. Here we report a case of AVM of cheek in an adult woman developed following a dental treatment. The diagnosis was confirmed by imaging and was treated surgically after angiography and embolization.
