Abstract

BACKGROUND:

Arteriovenous malformation of the scalp resulting from blunt trauma to the head is an unusual occurrence and is rarely associated with neurological sequelae. This case details an arteriovenous malformation with a cerebral steal phenomenon.

METHODS:

A 21-year-old man presented with an enlarging, pulsatile mass in the right facial/temporal area without known cause. CT and angiography were consistent with a large arteriovenous malformation involving the external carotid system, causing a secondary cerebral steal that resulted in neurological symptoms including seizure. Surgical resection of the mass was undertaken.

RESULTS:

The patient had an uncomplicated preoperative course with complete resolution of all neurologic symptoms.

CONCLUSION:

Cerebral steal is an uncommon consequence of traumatic extracranial arteriovenous malformation. The current literature is reviewed, and the diagnostic approach as well as therapeutic options are discussed.
