Figure 17. Esophageal intramural pseudodiverticulosis. Double-contrast esophagogram shows a moderately long stricture in the upper thoracic esophagus (straight solid arrows). Note the tiny esophageal intramural pseudodiverticula (curved solid arrows) at and below the level of the stricture. Note also the intramural tracking of barium between adjacent pseudodiverticula (open arrows). Despite the dramatic radiographic findings in such cases, a localized cluster of pseudodiverticula in the distal esophagus in the region of a peptic stricture is actually more common (cf Fig 1).
