Retrosternal densities are not included in the usual differential diagnosis of anterior mediastinal lesions or extrapleural thoracic diseases. The radiographic features of a retrosternal density, as ascertained primarily from lateral chest films, are usually sufficiently distinct to place it in the retrosternal-premediastinal space. The differential diagnosis of lesions in this arbitrary area is dependent upon an appreciation of the anatomical structures involved and their radiographic patterns. Several examples are illustrated.
