Intramural pseudodiverticulosis of the esophagus: report of seven cases and literature review.

Seven cases of esophageal intramural pseudodiverticulosis (EIPD) are presented and compared with 46 cases previously reported. EIPD is mainly a disease of older age with a 3:2 predominance of male patients. The radiologic appearance of EIPD shows great variation in localization and severity of visible changes. Radiologic examination is far more sensitive than endoscopy in diagnosing EIPD. The most effective therapy for EIPD is dilatation of strictures, leading to amelioration or disappearance of symptoms in over 90% of cases. Visible pseudodiverticula may persist after therapy, even in symptom-free patients.
