Among varieties of the mediastinal tumors, benign developmental cysts [Entergenous cysts] occur about 10% of them. From the primitive foregut, tracheobronchial tree and esophagus develop at 3 weeks of its embryonal age, and bronchogenic cyst arises from accessory or supernumerary lung bud. Usually it remains isolated with surrounding structures, and causes no specific symptoms. But few cases of bronchogenic cysts have fistulous communication with esophagus causing compressive symptoms. We report a case of unusual complicated case of bronchogenic cyst with review of literatures.
