Traumatic pseudoaneurysm of the superficial temporal artery: case report.

A 26 year-old woman suffered a blunt head injury on the left temporal area and developed an arteriovenous fistula with a pseudoaneurysm on the superficial temporal artery. These fistulas are rare and usually associated with pseudoaneurysms, most commonly in the frontal arterial branch. The aneurysms generally appear late after trauma and present as a pulsatile painfully growing mass in the temporal region, associated with fremitus and bruit.
