Radiologic

1.Single-contrast barium examination with low-density barium, which more readily enters the gland ducts, is more sensitive than a double-contrast technique with high-density barium for detecting intramural pseudodi-verticula. Endoscopy is relatively insensitive because it is difficult to visualize the tiny duct orifices.

2.The characteristic appearance is that of numerous small (1 to 4 mm), flask-shaped outpouchings from the esophagus. The tiny necks may not fill completely, resulting in an apparent lack of communication with the esophageal lumen.

image Distribution is more often segmental than diffuse. Pseu-dodiverticula may occur at, above, or below the level of a stricture.

3.Strictures associated with intramural pseudodiver-ticula should be evaluated carefully for evidence of malignancy.
