[Intraluminal diverticulum of the esophagus. Case report].

Intraluminal diverticulum of the esophagus is exceptive. It characteristic radiograhic appearance is of a smooth ovoid collection of barium surrounded by a smooth, thin radiolucent line. The diverticulum was plainly within the esophageal lumen. The diverticulum was not demonstrated on every barium study. One case of a 79 year old goitred female with intraluminal esophageal diverticulum is reported. Possible causes are considered.
