Esophageal Intramural Pseudodiverticulosis.

Esophageal intramural pseudodiverticulosis (EIPD) is an uncommon esophageal abnormality that is best diagnosed with a barium esophagram. The disorder is usually associated with other esophageal pathology, including strictures, motility disturbances, and other conditions that are outlined later. There is no specific treatment (either surgical or medical) for EIPD itself, and treatment should be directed at the underlying, associated conditions. If this condition is diagnosed on a barium study, endoscopy usually is needed to treat an associated stricture or to diagnose an associated inflammatory condition (particularly acid reflux and esophageal infections). Thus, endoscopy and barium studies are critical to guide the management of this condition.
