Subcutaneous emphysema may occur as a result of surgery, trauma or infectious process, air is forced beneath the tissue and spread along the fascial planes. Conditions that increase intra-thoracic pressure such as excessive coughing, vomiting, sneezing or prolonged Valsalva maneuver may result in volutrauma, with subsequent subcutaneous emphysema. Due to its unclear presentation, diagnosis of subcutaneous emphysema may be delayed or even missed. In this report, a case of subcutaneous emphysema, after stress shouting and prolonged bout of coughing, is presented. Imaging studies were consistent with a diagnosis of subcutaneous emphysema. The patient responded positively to conservative treatment and discharged uneventfully. The clinical manifestations, pathogenesis and management of subcutaneous emphysema are discussed together with review of literature.
