Computed tomographic features of esophageal intramural pseudodiverticulosis.

A patient with esophageal intramural pseudodiverticulosis (EIPD) was examined with computed tomography (CT). CT demonstrated marked thickening of the esophageal wall, diffuse irregularity of the esophageal lumen, and intramural gas collections--features typical of this entity. In the proper clinical setting, CT can confirm the diagnosis of EIPD, especially when other studies are equivocal. However, this case also demonstrates some of the limitations of CT in differentiating benign and malignant esophageal disorders.
