Spontaneous Pneumomediastinum: An Unusual Pulmonary Complication in Anorexia Nervosa.
Spontaneous pneumomediastinum (PM) is an uncommon condition in which free air enters the mediastinum. This usually occurs either through esophageal tears after vigorous vomiting, or after alveolar rupture subsequent to a rapid increase in intra-alveolar pressure. Spontaneous PM is a rare entity in anorexia nervosa (AN) and self-induced vomiting is often the cause of PM in patients with AN. We experienced a case of spontaneous PM in an anorexic adolescent, in whom vomiting was not the cause of PM.
