AbstractBlunt cerebrovascular injury is a very rare complication of blunt trauma and a diagnostic challenge. A 14 year old male fell 10 m sustaining multi system trauma. The atypical Glasgow Coma Score was six with a fully preserved eye component. Initial whole-body CT scanning demonstrated multiple injuries but no obvious brain injury. Trauma management involved non-operative resuscitation and was successful, however profound coma occurred and brain stem reflexes disappeared on day two. Repeat brain CT scan demonstrated multiple cerebral and cerebellar ischemic lesions and no opacification of the vertebral or basilar arteries. Secondary analysis of the first CT scan demonstrated a small focal basilar artery dissection not initially reported. Our case report highlights an unusual cause of coma after traumatic brain injury where the clinical scenario mimics locked in syndrome. In such circumstances cerebrovascular injury, and in particular traumatic basilar artery dissection, must be actively excluded.Copyright © 2021 Elsevier Inc. All rights reserved.
