Abstract

We report a case of combined traumatic pseudoaneurysm and arteriovenous fistula of the middle meningeal artery, which presented clinically 1 year after initial head trauma. A 39-year-old male presented with seizure activity after a closed head injury from a fall. He was hospitalized for multiple intraparenchymal hemorrhages and ultimately discharged 2 weeks later without neurologic deficits. One year later, he presented with a new right anterior temporal intraparenchymal hemorrhage after a syncopal event. Selective angiography of the right external carotid artery demonstrated a chronic appearing traumatic laceration of the proximal middle meningeal artery with a 6 × 10 mm pseudoaneurysm and a single fistula with venous varix draining into the lateral pterygoid veins. The pseudoaneurysm and arteriovenous fistula were successfully embolized with n-butyl cyanoacrylate.
