abstract="A previously healthy 20-year-old male trainee developed chest pain, shortness of breath, and neck pain after repeatedly shouting &quot;Hooah!&quot; during a motivational squad competition. He was found to have developed a pneumomediastinum with soft tissue crepitus of the neck. He had an uneventful recovery. Unique to the military training environment, vigorous shouting, including &quot;Hooah!&quot; as a motivational stimulus, can have barotraumatic consequences. The term &quot;spontaneous&quot; as applied to a pneumomediastinum diagnosis is examined and the auscultatory finding of &quot;Hamman's sign&quot; is reviewed.<p /> <p>Language: en</p>",
