Nodes associated with the diaphragm interconnect with parasternal, prevertebral, and juxta-esophageal nodes, brachiocephalic nodes (anterior to the brachiocephalic veins in the superior mediastinum), and lateral aortic/lumbar nodes (in the abdomen).
Superficial regions of the thoracic wall drain mainly into axillary lymph nodes in the axilla or parasternal nodes.
