Lethal rupture of post-traumatic aneurysm of the vertebral artery case report.

Abstract Traumatic aneurysms or dissections of the vertebral artery have been reported in patients who have suffered minor craniofacial injuries in traffic accidents. A case is reported of ruptured traumatic vertebral artery aneurysm due to closed head injury without without penetrating injuries or skull fractures. The macroscopic and histological findings relevant to the vertebral wall were compatible with post-traumatic aneurysm; the rupture of the wall was assumed to be caused by sepsis and local infiltration of inflammatory cells.
