Blunt chest trauma with post-traumatic tracheobronchial rupture is a rare (0.5-5%) but life-threatening injury. In 25-68% of the cases, the diagnosis of blunt main stem bronchus injuries is delayed, which may lead to complete bronchial obstruction and atelectasis 6 to 21 days after the rupture. Clinical manifestations are variable and non-specific, and 10% of the patients are asymptomatic. An early diagnosis is paramount to reduce its morbidity and mortality. This clinical case emphasizes the major role of flexible bronchoscopy in the approach of patients with blunt chest trauma.
