A large arteriovenous malformation of the external ear in an adult: report of a case and approach to management.
OBJECTIVE
Arteriovenous malformations involving the external ear are relatively uncommon in adults. Arteriovenous malformations in the head and neck can poses difficult therapeutic challenges.


METHODS
Case report.


METHODS
We report a case of a large arteriovenous malformation in the external ear in a 41-year-old man.


RESULTS
Extensive enlargement of the previously latent and asymptomatic arteriovenous malformation was triggered by blunt trauma to the ear.


CONCLUSIONS
We discuss the definition, clinical findings, diagnostic approaches, and therapeutic management of arteriovenous malformations.
