[Esophageal intramural pseudodiverticulosis (author's transl)].

Esophageal Intramural Pseudodiverticulosis (EIP) is a very rare disease, which may affect patients of all age. EIP is characterized by dilatation of the esophageal submucosal glandular elements. The characteristic radiographic appearance supported by endoscopy makes the diagnosis. Stenosis and motility disturbance caused by secondary chronic esophagitis due to EIP were found in most patients. The etiology of EIP is unknown.
