Pneumomediastinum
Alternate Names : Mediastinal emphysema
Symptoms & Signs
There may be no symptoms. The condition usually causes chest pain below the breastbone, which may spread to the neck or arms. The pain may be worse when you take a breath or swallow.
Diagnosis & Tests
During a physical examination, the doctor may feel small bubbles of air under the skin of the chest, arms, or neck. A chest x-ray or CAT scan of the chest may be done to confirm the presence of air in the mediastinum and help diagnose a hole in the trachea or esophagus.
