The mediastinum, though a small anatomic compartment, contains more vital structures than any other compartment in the body. Practically every organ system is included in this area. The lesions that arise from these systems are many, yet they may so closely resemble each other that they almost defy differentiation. The lesions are similar as they produce the same symptoms and have similar roentgenographic features. An attempt to separate these lesions by their symptoms would prove discouraging. The best approach is by their roentgenographic appearance.

The authors first discuss the normal roentgenographic features of the mediastinum and its contents. From this point the various mediastinal tumors are dealt with according to the organ systems from which they arise. Only the diagnostic features are discussed and illustrated by numerous roentgenograms gathered from many sources. The lesions are not discussed from therapeutic or prognostic viewpoints. This is justifiable as the purpose of the
