Esophageal intramural pseudodiverticulosis (diffuse type).
A rare case of esophageal intramural pseudodiverticulosis (EIPD) in a 65-year-old woman with intermittent dysphagia is reported. An upper gastrointestinal series revealed multiple pseudodiverticula, which had tiny flask-shaped outpouchings with a narrow neck extending outward from the upper to the lower thoracic esophageal wall. In particular, the occurrence of the pseudodiverticula was coincident with a narrowed segment of inflamed esophagus. The length of the esophagus involved was approximately 15 cm. Endoscopic findings included mild stricture and chronic inflammation of the mucosa. Biopsy specimens showed active chronic esophagitis with bacterial and Candida superinfection, but no evidence of neoplasm. Cellular local immune reactions, as a consequence of chronic inflammation, and possibly abnormal motor activity in the narrowed esophagus, may explain the etiological agent or may be possible secondary factors that caused the EIPD.
