In brief: Air between lungs
The mediastinum is in the center of the chest between the two lungs containing the heart, esophagus, trachea and great blood vessels.
Air in the mediastinum (pneumomedistinum) can occur from a perforated esophagus, trauma, severe asthma with alveolar rupture, after surgery, or in barotrauma in scuba diving . The underlying cause may need to be treated emergently.
