Congenital stenosis of the duodenum secondary to duodenal web is a rare and predominantly pediatric condition due to incomplete recanalization of the duodenal lumen during early gestation. The windsock appearance on a fluoroscopic examination of the upper gastrointestinal tract is pathognomonic for obstructive processes in the duodenum. Here, we report a surgically proven case of duodenal web in an infant.
