title: Congenital biparietal foramina presenting with multiple concussions.
abstract: We report a man with biparietal foramina secondary to Potocki-Shaffer syndrome. This is due to incomplete ossification of parietal bones secondary to haploinsuffiency of ALX4 gene. He presented with multiple episodes of concussion following minimal head trauma. Cranioplasty was performed to close the skull defects with the aim of preventing further concussion and permanent traumatic brain injury.
