Esophageal intramural pseudodiverticulosis is a rare condition of unknown etiology originally described in 1960. It is characterized by multiple, flask-shaped outpouchings of pinhead size in the wall of the esophagus. Very small outpouchings on endoscopy and tiny collections of barium outside of the esophagus wall on esophagography are typical diagnostic findings. During the era of widespread endoscopic and radiological evaluation of esophageal disorders, approximately 200 cases were published in the literature. A 52-year-old man with esophageal intramural pseudodiverticulosis with food impaction is reported. The patient’s symptoms of dysphagia resolved with endoscopic dilations and proton pump inhibitor therapy.
