title: Axillary lymphadenopathy simulating an anterior mediastinal mass on the lateral chest roentgenogram.
abstract: The radiographic impression of an anterior mediastinal mass on the lateral chest roentgenogram must be confirmed by the postero-anterior film, oblique views, or tomograms to avoid inappropriate diagnostic procedures or erroneous staging of malignant disease. Physical examination will readily demonstrate enlarged axillary lymph nodes mimicking an anterior mediastinal mass.
