Respiratory system

Mediastinal emphysema

There may be no symptoms. The condition usually causes chest pain behind the breastbone, which may spread to the neck or arms. The pain may be worse when you take a breath or swallow.

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 CT scan of the chest may be done to confirm that there is air in the mediastinum, and help diagnose a hole in the trachea or esophagus.
