A case of gastric outlet obstruction secondary to prepyloric antral web in a four-year-old boy with cerebral pareses is reported. Routine roentgenographic examination was initially misinterpreted as duodenal obstruction. Prepyloric antral web was suspected by subsequent endoscopy and was confirmed by operation. The patient underwent antropyloroplasty that resulted in excellent recovery. The possibility of a prepyloric antral web should be considered in any infant or child with persistent vomiting when pyloric stenosis is excluded.
