[Intramural pseudodiverticulosis of the esophagus]

Esophageal intramural pseudodiverticulosis is a rare condition of yet unknown etiology. Histologic findings of pseudodiverticulosis are characterized by dilated submucosal mucous glands in the esophagus wall. The clinical features including slowly progressive dysphagia mimic those of esophageal carcinoma. The diagnosis is established by radiologic examination, revealing numerous tiny outpouchings of the esophagus wall filled with contrast material. Endoscopic biopsy of the frequently associated stenosis of the upper esophagus is mandatory. Computer tomography shows localized thickening of the esophagus wall. Manometry reveals motoric dysfunction. Etiology and therapeutic management are discussed.
