‘Brain Tissue Out’ in a Train Struck Victim: A Case Report

Background: ‘Brain tissue out’ (BTO) is used here to describe traumatic acute extracranial cerebral herniation, an extreme manifestation of severe TBIs. Case Description: We report a case of a 15-year-old victim of a severe head injury who was brought with acute extracranial cerebral herniation ‘brain tissue out’. We review the current literature and evidence of this exceedingly rare presentation. Conclusion: 'Brain tissue out' is a rare form of severe head injury with a very poor prognosis. The possible catastrophic short long-term effects of this injury warrant further attention to clarify the underlying mechanisms and to identify its management guidelines.
