Duodenalulkus

Peptic

duodenal stricture causing gastric outlet obstruction: CT diagnosis with endoscopic correlation. Coronal images (c, detail d) confirmed overdistended stomach with stagnant fluid (*). The pylorus and proximal duodenum showed circumferential hypoenhancing mural thickening (+) and depressed focal thinning of enhancing mucosal contour (thin arrows).
