Spontaneous Pneumomediastinum in Non-Asthmatic Children with Exercise-Induced Bronchoconstriction.
Subcutaneous emphysema can result from rupture of the respiratory or gastrointestinal systems, commonly occurring after trauma or surgery, as well as from rupture of alveoli as pneumothorax or pneumomediastinum. Spontaneous pneumomediastinum with subcutaneous emphysema is rare in children without chest or neck trauma. Here, we report 2 cases of spontaneous pneumomediastinum with exercise-induced bronchoconstriction. ⋯ Early recognition and investigation of serious conditions should be promptly done in spontaneous pneumomediastinum patients. Conservative treatment, extensive investigations of predisposing factors, and treatment are important.
