The Retrotracheal Triangle

Louis Raider M.D., F.C.C.P.1

1 Director, Department of Radiology, Providence Hospital, Mobile, Alabama

The retrotracheal triangle is the posterior superior mediastinum. This may be the site of significant findings in greater than 1 percent of all chest radiographs. The anatomy of the space is reviewed and many of the interesting abnormalities occurring in this area are described. These include vascular abnormalities, esophageal lesions and a variety of masses representing tumors, cysts, sequelae to trauma, inflammatory processes and emphysema. Among those considered are the aberraut right sUbclavian artery, the right aortic arch, the double aortic arch, Zenker's diverticulum, carcinoma of the esophagus, Congenital atresia of the esophagus, foreign bodies and thyroid masses. Careful attention to this area should be rewarding to the observer.
