abstract: Air filled oesophagus is a well known condition occurring in sclerodermia, megaoesophagus, neoplasms or in association with wall adhesion following pulmonary diseases, mediastinitis, and in the postsurgery thorax. Besides cases reported as presbioesophagus, in old people, air may fill oesophagus because pressed and diverted by a widened aorta. The radiological appearance of such a condition has been described variable in the previous reports. In our observations however the features were characterized by a radiolucent band parallel to trachea and to left bronchus.
