Traumatic Pseudoaneurysm Related to Calcified Nodules of Cerebral Convexity Dura Mater in an American College Football Player.

Repeated concussion is common among football players; however, these minor blunt head trauma rarely result in serious complications. We report a case of a young college football player who presented acute subdural hematoma, cerebral edema, and seizure due to pseudoaneurysm rupture. The pseudoaneurysm, located at the cortical branch of the middle cerebral artery, was speculated to be formed by dural calcification and adhesion with the underlying brain, possibly due to repeated concussions. Following successful excision of the pseudoaneurysm and control of brain swelling, the patient recovered without sequelae and was discharged after a short while.
