title: Esophageal intramural pseudodiverticulosis complicated with stricture.
abstract: We report a rare case of diffuse esophageal intramural pseudodiverticulosis in a 35-year-old man complaining of severe dysphagia and vomiting for several months. The advanced morphological change in the esophagus caused irregular track formation, mimicking an ulcerative lesion on esophagogram. Endoscopic examination revealed an esophageal stricture with intact mucosa. Endoscopic ultrasonography and chest computed tomography showed multiple hyperechoic lesions of unknown nature and multiple air collection sites in the esophageal wall, respectively, making diagnosis difficult. The patient finally received a subtotal esophagectomy because of severe symptoms. The lesion was pathologically proven to be intramural pseudodiverticulosis with marked submucosal fibrosis. Our experience suggests that awareness of this rare pathology and the related image changes will be helpful for early diagnosis and treatment in the future.
