A 65-year-old female was admitted into our department with complaint of bloody sputum. An upper G-I series examinations and thoracic CT demonstrated an esophago-bronchial fistula with diverticulum located between the mid-esophagus and right B6. Following postero-lateral thoracostomy, the fistula was surgically removed and right lower lobectomy was carried out. No inflammatory changes were found in the surrounding tissues of the fistula and the diverticulum. Histological examination revealed that the fistula wall contained squamous epithelium and muscularis mucosa. These results suggested that this case was congenital esophago-bronchial fistula categorized as Braimbridge type I.
