Pneumomediastinum: etiology and a guide to diagnosis and treatment.
Pneumomediastinum may be associated with mediastinal organ injury. The aim of this study was to identify predictive factors of mediastinal organ injury in patients with pneumomediastinum to guide diagnosis and treatment. ⋯ Mediastinal organ injury in patients with pneumomediastinum is uncommon. Patients presenting with pneumomediastinum without a history of instrumentation, pleural effusion, or vomiting most commonly do not have mediastinal organ injuries.
