Tracheobronchial disruption is a rare injury associated with blunt trauma, and for proper management, accurate diagnosis is essential. We describe a case of isolated tracheal rupture following blunt trauma, and the related CT findings, including details of the injury site. Preoperative bronchoscopy was not performed, but the patient immediately underwent surgery, which was successful. This case demonstrates that CT scanning is very helpful both for diagnosis of tracheobronchial injury and for delineation of the exact injury site.
