anterior mediastinal lymph nodes (anteroinferior)

Last reviewed 01/2018

The anterior group of the anterior inferior mediastinal lymph nodes are a group of 2-3 nodes on each side sited at the anteromedial surface of the diaphragm near to the sternocostal hiatus.

They receive afferent lymphatics from the:

  • anterior region of the diaphragm
  • adjoining pleura
  • upper abdominal viscera

They send efferent lymphatic vessels superiorly to merge with the sternal lymphatic chains.
