We report 3 cases of spontaneous mediastinal emphysema. All patients were young males, and had predisposing episodes for development of spontaneous mediastinal emphysema; sports in 2, loud voice in 1. ⋯ All patients became asymptomatic with mediastinal air reabsorption within a week. We should recognize spontaneous mediastinal emphysema as one cause of chest, back, neck and epigastric pain.
