A Rare Coincidence of Esophageal Intramural Pseudodiverticulosis with Esophageal Web

We report a rare case of esophageal intramural pseudodiverticulosis (EIPD) associated with esophageal web in a 67-year-old man presenting with dysphagia. EIPD is characterized by multiple tiny flask-shaped outpouchings of the mucosa that extend into the muscular layer on esophagography. EIPD commonly presents with stricture and less commonly with esophageal web. Although etiologies of both EIPD and esophageal web are unclear, a chronic inflammatory condition has been proposed. Treatment of EIPD is usually directed at the associated conditions rather than at the pseudodiverticulosis itself. In our case, dysphagial was successfully relieved by endoscopic dilatation with incision methods for the esophageal web. (Korean J Helicobacter Up Gastrointest Res 2015;15:196-199)
