Pseudoweb of the gastric antrum in infants.

Two infant boys, one 3 months of age and the other 8 weeks of age, with symptoms suggesting gastric outlet obstruction had upper gastrointestinal fluororadiographic examinations which showed typical signs for gastric antral webs (diaphragms or membranes), but neither had actual webs as proven by surgery in one and by endoscopy in the other. The report emphasizes the possibility of falsely positive radiographic findings, which can be tested by potentially corroborative fiberoptic endoscopy, thus avoiding unnecessary surgery.
