Figure 1. Peptic stricture with esophageal intramural pseudodiverticula. Double-contrast esophagogram shows a smooth, tapered area of concentric narrowing in the distal esophagus (large arrow) above a hiatal hernia. This is the classic appearance of a peptic stricture. Note also the tiny esophageal intramural pseudodiverticula in the region of the stricture (small arrows). Some of the pseudodiverticula seem to be "floating" outside the wall of the esophagus without direct communication with the lumen, a characteristic radiographic feature of these structures.
