This system classifies mediastinal nodes into four groups or zones known as (1) the upper zone (paratracheal and prevascular nodes), (2) the aortopulmonary zone (aortopulmonary window nodes), (3) the subcarinal zone (subcarinal nodes), and (4) the lower zone (paraesophageal and inferior pulmonary ligament nodes). Each of these presentations is managed differently, as described below.
