We report a rare case of esophageal intramural pseudodiverticulosis with esophageal strictures. Barium esophagogram demonstrated multiple flask-shaped diverticula out of the esophageal wall with comprehensive luminal stenosis involving the proximal 8 cm and distal 4 cm of the esophagus. Chest computed tomographic scan demonstrated round wall thickening and several intramural gas collections of the proximal esophagus. Endoscopy revealed a fibrotic stricture and multiple small orifices of pseudodiverticula with mild inflammatory changes. Biopsy specimens showed active chronic inflammatory changes of the mucosa with candidiasis. Dysphagia improved dramatically with esophageal dilation. However, the tiny diverticula did not resolve after treatment.

Comment

Esophageal intramural pseudodiverticulosis was first reported by Mendl and coworkers [1] in 1960; since then only 220 cases have been reported worldwide [2]. The condition is a little more common in males than females (ratio, 3 males to 2 females), and the mean age of the patients at the time of diagnosis is 53.5 years (range, 0.75 to 86 years) [3]. Esophageal intramural pseudodiverticulosis commonly presents with dysphagia, such that 47% of the patients have constant symptoms, 24%
