The pretracheal lymph nodes are classified into pretra- cheal, retrotracheal, and anterior mediastinal lymph nodes; the pretracheal lymph nodes are located caudal to the superior mediastinal lymph nodes, at the anterior wall of trachea, and are present on the posterior wall of the vena cava superior and the posterior …
Are paratracheal nodes mediastinal?
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.
Where is the right paratracheal located?
The right paratracheal stripe is a normal finding on the frontal chest x-ray and represents the right tracheal wall, adjacent pleural surfaces and any mediastinal fat between them. It is visible because of the silhouette sign created by air within the trachea medially and air within the lung laterally.
