Esophageal intramural pseudodiverticulosis treated by endoscopic balloon dilatation.

We here report a rare case of esophageal intramural pseudodiverticulosis with dysphagia. A 65-year-old man was suffering from intermittent dysphagia for 10 years, which had been worsening in recent months. Endoscopic examination revealed multiple, small, saccular diverticula and mild annular stricture with numerous white plaques from the cervical esophagus to the middle thoracic esophagus. Barium esophagography revealed stricture of the upper thoracic esophagus with multiple tiny flask-shaped outpouchings. Based on this characteristic appearance, we diagnosed esophageal intramural pseudodiverticulosis and inflammation of a narrow segment of the esophagus. Biopsy specimen showed acute and chronic esophagitis with Candida infection. Dysphagia persisted despite resolution of candidiasis, for which we successfully performed endoscopic balloon dilatation of the stricture. After the treatment, the patient has been well and has not been suffering from dysphagia.
