Gastric pneumatosis secondary to pyloric stenosis.

Pneumatosis of the intestine is a concerning radiographic finding which may be indicative of intestinal ischemia or necrosis. Gastric pneumatosis is particularly rare, and in neonates, is usually associated with necrotizing enterocolitis. There are rare reports of gastric pneumatosis being associated with other non-ischemic etiologies. Herein, we report a 4 week old neonate who presented with persistent emesis. Abdominal radiographs showed extensive gastric pneumatosis. Further workup revealed pyloric stenosis that responded to standard surgical therapy.
