AbstractEsophageal intramural pseudodiverticulosis (EIPD) is a rare condition in which multiple small outpouchings are seen in the wall of the esophagus. Although EIPD is typically associated with esophageal narrowing, only a few cases have been described in which it was associated with esophageal dysmotility. We report the case of a 52-yr-old female who presented with dysphagia and who had EIPD protruding from a 5-cm-long concentric distal esophageal stricture, with a markedly dilated upper and middle third of the esophagus. The short segment of the esophagus between the stricture and the lower esophageal sphincter also was dilated. Barium column was held up above a nonrelaxing lower esophageal sphincter that opened after inhalation of amylnitrate. Esophageal manometry confirmed the presence of vigorous achalasia. Although EIPD has been associated with several other conditions, this is the first report of an association with achalasia.
