N2

Fig. 24: Diagram, N2 disease. Enlarged ipsilateral mediastinal lymph nodes (>1 cm.) indicate and are classified clinically as N2. However, because all enlarged lymph nodes do not contain metastasis, objective assessment of the nodes is advised to confirm N2 disease in patients who may be candidates for surgery.

 

Fig. 25a & b: a) Posterior-anterior chest radiograph shows a mass with irregular borders and infiltrate in the right upper lobe. b) Computed tomographic scan of the chest delineates the right upper lobe mass and enlarged lower paratracheal nodes (white arrow), N2 disease.
