Spontaneous tracheal rupture is one of the rare life threatening conditions. Tracheal lacerations are generally secondary to cervical or chest trauma or occurring as a complication of endotracheal intubation. Spontaneous trachea-bronchial tree injury (TBI) are potential killers if not diagnosed early and treated adequately. We hereby report 2 case reports of spontaneous TBI, one secondary to a lower respiratory tract infection (LRTI) and the other secondary to COPD with long term steroid use. There are only less than 5 case reports till date, published on spontaneous TBI.
