Peri Aortic lymph nodes are also called Lumbar Lymph nodes.
The PeriAortic or Lumbar lymphnodes contain:
- ParaAortic lymph nodes
- ParaCaval lymph nodes
Lymphatic drainage of gonads
Gonads include both testes and ovaries.
Please read the following statements to understand the concept of lymphatic drainage of gonads.
- Gonads drain into PeriAortic Lymph nodes
- Gonads drain into lumbar lymph nodes
- Left gonads (testes & ovaries) drain into ParaAortic (note, not periaortic, paraAortic is also part of peri aortic) lymph nodes
- Right gonads (testes and ovaries) drain into ParaCaval lymph nodes (caval refers to inferior venacava)
- The right (paracaval) and left (paraaortic) lymph nodes and lymphatic system anastomoses alot, so infection or metastasis in one can reach the other too
ParaAortic lymph nodes
Left lumbar or ParaAortic lymph nodes contain:
- Lateral aortic lymph nodes
- Preaortic lymph nodes
- Postaortic lymph nodes
- Intermediate lumbar lymph nodes
ParaCaval lymph nodes
Right lumbar or ParaCaval lymph nodes contain:
- Lateral caval lymph nodes
- Precaval lymph nodes
- Postcaval lymph nodes
