CT diagnosis of bronchial rupture.

Computed tomography in a patient with unsuspected rupture of the left mainstem bronchus revealed shift of the trachea to the right, with the remainder of the mediastinum being shifted to the left. The left mainstem bronchus was visualized only in its most proximal course. The combination of deviation of the trachea from the remainder of the mediastinum and abrupt cut off of the left mainstem bronchus suggested the diagnosis of ruptured bronchus.
