title: The trachea: the blind spot in the chest.
abstract: This article emphasizes diagnostic importance of careful observation of the size, position, and luminal air column of the trachea in the interpretation of the chest roentgenogram. The changes described provide information about intratracheal lesions and help in localization and differential diagnosis of mediastinal masses.
