Sarcoidosis (see: pulmonary manifestations of sarcoidosis) The spectrum of conditions that can result in mediastinal lymphadenopathy is extremely diverse and includes:

Moreover, disease begins in normal sized lymph nodes which enlarge with disease progression. Ideally, the term lymphadenopathy would be applied only to diseased lymph nodes however this distinction may require pathological analysis. The term mediastinal lymphadenopathy implies lymph node disease and is not synonymous with mediastinal lymph node enlargement. Enlarged lymph nodes may be simply reactive as in most bacterial pneumonias, or diseased due to invasion by e.g.

Small shotty lymph nodes
