We encountered 3 patients with spontaneous pneumomediastinum. The patients were a 14-year-old female, a 16-year-old male and an 18-year-old male. All 3 were previously healthy. ⋯ All patients were treated with rest and all recovered in 7 to 9 days without any complication. Spontaneous pneumomediastinum is an uncommon, usually benign, self-limited disorder that usually occurs in young adults without any apparent precipitating factor or disease. Most patients require only conservative treatment.
