title: Intraluminal esophageal diverticulum.
abstract: An intraluminal esophageal diverticulum (IED) is an uncommon entity defined as a double-layered mucosal pouch lying within the lumen of the esophagus. Its characteristic radiological finding is an intraluminal barium collection surrounded by a radiolucent halo. True IED, which is different from a transient radiological artifact, has not been previously reported in the international literature. This article describes the first case of true IED. Differential diagnosis between a true lesion and a transient flow artifact on barium meal is discussed.
