Vomiting-induced gastric emphysema: a rare self-limiting condition.

Radiological evidence of presence of air or gas within the stomach wall is termed "gastric pneumatosis" and is considered an ominous sign. However, the etiological associations range from benign self-limiting causes to life-threatening emergencies. The authors report the case of gastric pneumatosis in a 34-year-old man who presented to the emergency department with severe abdominal pain after multiple episodes of vomiting. The authors also review the clinical associations of this uncommon condition and discuss risk stratification and management strategies.
