title: Traumatic subarachnoid hemorrhage and extracranial vertebral artery injury: a case report and review of the literature.
abstract: The case is presented of a 19-year-old man who was assaulted and died shortly afterward from a large traumatic basal subarachnoid hemorrhage (TBSAH) that arose from rupture of the left vertebral artery, proximal to the point at which the artery penetrated the dura. The literature regarding TBSAH and vertebral artery rupture is reviewed, and a number of points are highlighted: patients with TBSAH may remain conscious for a period of hours after injury, subcutaneous or muscular bruising may be contralateral to the ruptured vessel, fractures of the transverse processes of the cervical vertebrae and significant pathology of the vertebral artery are not typically associated with TBSAH, and rupture of the vertebral artery may be intracranial, junctional, or extracranial.
