title: Delayed bronchostenosis after blunt chest trauma in children: CT and pathologic findings.
abstract: Tracheobronchial disruption is an uncommon injury associated with blunt chest trauma. We report CT features and pathologic findings of two pediatric cases in which a bronchial injury was unnoticed initially but was diagnosed later by appearance of delayed bronchostenosis with distal atelectasis after blunt chest trauma in recent motor vehicle accidents. Pathologically, obliteration of the bronchial lumen was caused by dense fibrous overgrowth and granulation tissue.
