A Rare Case of Spontaneous Pneumomediastinum in a Female After Shouting: A Literature Review.

Spontaneous pneumomediastinum (SPM) is a rare self-limiting benign condition that manifests as free air in the mediastinum without any underlying etiology. This under-reported diagnosis occurs usually in young males, with few reports in females. Here, we present a case of a 17-year-old healthy female who presented to the emergency department (ER) with shortness of breath (SOB) and chest pain preceded by an episode of shouting. And she was identified to have SPM and subcutaneous emphysema (SE).
