Bottom Line: Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome.Currently used lymph node maps have been reconciled to the internationally accepted International Association for the Study of Lung Cancer (IASLC) map published in the seventh edition of TNM classification system of malignant tumours.This article provides computed tomographic illustrations of the IASLC nodal map, to facilitate its application in day-to-day clinical practice in order to increase the appropriate classification in lung cancer staging.

ABSTRACT
Accurate lymph node staging of lung cancer is crucial in determining optimal treatment plans and predicting patient outcome. Currently used lymph node maps have been reconciled to the internationally accepted International Association for the Study of Lung Cancer (IASLC) map published in the seventh edition of TNM classification system of malignant tumours. This article provides computed tomographic illustrations of the IASLC nodal map, to facilitate its application in day-to-day clinical practice in order to increase the appropriate classification in lung cancer staging.

Station 5. (A) The upper border of station 5 is the lower border of aortic arch (AoA), and lower border is the upper rim of the left main pulmonary artery (PA). (B) The border between station 4L and station 5 is the ligamentum arteriosum (sky-blue arrow). Station 4L nodes locate medial to the ligamentum arteriosum (blue arrow), and station 5 is the lymph node lateral to the ligamentum arteriosum (brown arrow). AA: ascending aorta; AZ: azygos vein; DA: descending aorta.

Figure 5: Station 5. (A) The upper border of station 5 is the lower border of aortic arch (AoA), and lower border is the upper rim of the left main pulmonary artery (PA). (B) The border between station 4L and station 5 is the ligamentum arteriosum (sky-blue arrow). Station 4L nodes locate medial to the ligamentum arteriosum (blue arrow), and station 5 is the lymph node lateral to the ligamentum arteriosum (brown arrow). AA: ascending aorta; AZ: azygos vein; DA: descending aorta.

Mentions: The medial border of station 5 is the ligamentum arteriosum (Figure 5), which is difficult to identify on axial CT unless calcified. The prevalence of ligamentum arteriosum calcification on CT is higher in children (37.8%) than in adults (11.2%) with peak prevalence in 6-10 years, afterwards declining with age12. Although usually invisible on CT the expected location can be estimated by identifying the closest position of the upper pulmonary artery and the aortic arch on coronal reconstructions.
