Gastric emphysema is a rare condition in which gas from a nonbacterial source accumulates within the wall of the stomach. Gastric distension and vomiting frequently precede the formation of the intramural air. Pulmonary disease, instrumentation of the stomach, and obstructing lesions of the antrum and pylorus are also common contributing factors. A case report and an extensive review of the literature are presented.
