Answer

Pneumomediastinum may be observed in pediatric patients (usually female) with anorexia nervosa. Hochlehnert et al note that starvation and malnutrition may predispose to structural changes within the lung interstitium, leading to the formation of bullae, emphysema, and bronchiectasis, which adds to the risk of spontaneous pneumomediastinum following vomiting.
