Arteriovenous malformation (AVM) occurs due to the failure of complete involution of the fetal capillary bed resulting in the development of abnormal connections between arteries and veins (arteriovenous shunting). The most frequent location of arteriovenous malformations in the head and neck is intracranial, they can also occur in the cheek and parotid, ear, nose, forehead, and neck regions. The ear is the second most common location in the head and neck. We report a case of giant AVM of the left pinna in an adolescent, which are very rarely seen. We discussing the definition, clinical findings, diagnostic approaches and therapeutic management of arteriovenous malformations.
