Subcutaneous emphysema and pneumomediastinum following cocaine inhalation: a case report.

Introduction: Subcutaneous emphysema or pneumomediastinum can occur as a complication of illicit drug use although this is rare. When occurring without a pneumothorax and spontaneously, it is usually treated conservatively, but can have serious consequences.

Case Presentation: Here, we present the case of an otherwise healthy 23-year-old Caucasian man who presented to the Emergency Department at our institution and was found to have both subcutaneous emphysema and pneumomediastinum as a result of cocaine use.
