Anatomy of Mediastinum


Differentiating Mediastinal Mass from other Diseases

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Trusha Tank, M.D.[2]


The mediastinum is a non-delineated group of structures in the thorax (chest), surrounded by loose connective tissue. It is the central compartment of the thoracic cavity. It contains the heart, the great vessels of the heart, esophagus, trachea, thymus, and lymph nodes of the central chest. A wide variety of diseases involving these organs can present as a mediastinal mass or widening of the mediastinum on imaging studies.


Following can appear as a mediastinal mass on imaging studies:

Cardiovascular causes
Gastrointestinal causes
Pulmonary causes
CNS diseases
Thyroid diseases
Mediastinal tumors
Cystic mass
