Esophageal intramural pseudodiverticulosis with esophageal cancer improved by target rotation irradiation: case report.

Etiology of esophageal intramural pseudodiverticulosis is still unknown but several accompanying diseases have been reported, for example, reflux esophagitis, esophageal cancer, diabetes mellitus and so on. We have experienced a case of esophageal intramural pseudodiverticulosis with cancer improved by radiation therapy. In this case, there were esophageal cancer in the cervical esophagus, with intramural spreading in whole esophagus. This case was delivered irradiation to the entire esophagus by target rotation method. After irradiation, intramural pseudodiverticula, intramural spreading and primary site of esophageal cancer were improved. This is an interest case report that esophageal intramural pseudodiverticula with cancer was disappeared by radiation therapy.
