The most commonly involved mediastinal lymph node stations are as follows: right paratracheal, aortopulmonary, tracheobronchial, distal bronchopulmonary, and subcarinal. These lymph node stations are usually easily accessible by bronchoscopy, allowing a high diagnostic yield of transbronchial needle aspiration.
