Imaging of tracheobronchial injuries.

Tracheobronchial injuries are rare and can be life threatening. They can result from external injuries due to blunt or penetrating trauma or from internal injuries subsequent to inhalation of fumes, gases, and aspiration of liquids or foreign bodies. The most dangerous aspect of tracheal trauma is the fact that it is easily overlooked initially. Imaging studies play a pivotal role in timely diagnosis.
