In This Section

1. What are the common iliac lymph nodes?

Groups of lymph nodes located along the common iliac blood vessels.

2. Where are the common iliac lymph nodes located?

Along the common iliac vessels near the pelvic brim and lumbosacral junction.

3. In which anatomical compartment are the common iliac lymph nodes situated?

The extraperitoneal connective tissue of the pelvis and lower retroperitoneum.

4. Which major arteries serve as anatomical landmarks for the common iliac lymph nodes?

The right and left common iliac arteries.

5. What are the three commonly described groups of common iliac lymph nodes?

Lateral, medial, and middle groups.

6. Where are the lateral common iliac lymph nodes located?

Along the lateral aspect of the common iliac vessels.

7. Where are the medial common iliac lymph nodes located?

Along the medial aspect of the common iliac vessels, near the sacral promontory.

8. Where are the middle common iliac lymph nodes located?

In the region between the common iliac artery and vein, particularly posterior to the artery.

9. Which major pelvic lymph node groups drain into the common iliac lymph nodes?

The external iliac and internal iliac lymph node groups.

10. Which lymph node group drains lymph from the sacral region toward the common iliac nodes?

The sacral lymph nodes.

11. Which lymph nodes receive lymph from the lower limb before it reaches the common iliac nodes?

The inguinal and external iliac lymph nodes.

12. How does lymph from the urinary bladder commonly reach the common iliac nodes?

Through the external and internal iliac lymph node groups.

13. Which lymphatic pathways carry lymph from the prostate toward the common iliac nodes?

Primarily pathways through the internal iliac, obturator, and sacral lymph nodes.

14. How can lymph from the uterine cervix reach the common iliac lymph nodes?

Through pelvic lymphatic pathways involving the internal iliac, external iliac, and sacral nodes.

15. Which part of the rectum may drain toward common iliac nodes through pelvic lymphatic pathways?

The middle and lower rectum, primarily through internal iliac lymphatic pathways.

16. Which major lymph node group receives efferent lymphatic vessels from the common iliac nodes?

The lumbar lymph nodes, also called para-aortic lymph nodes.

17. Which lymphatic trunks carry lymph from the lumbar lymph nodes toward the central lymphatic system?

The right and left lumbar lymphatic trunks.

18. Which lymphatic reservoir commonly receives lymph from the lumbar trunks?

The cisterna chyli, when present.

19. What is the principal function of the common iliac lymph nodes?

To filter lymph arriving from pelvic and lower limb drainage pathways before it reaches the lumbar lymph nodes.

20. Why are common iliac lymph nodes important in pelvic cancer staging?

They can contain metastatic tumor cells spreading through pelvic lymphatic pathways.

21. Which gynecological malignancy commonly requires assessment of common iliac lymph nodes during staging?

Cervical cancer.

22. Why are common iliac lymph nodes relevant during pelvic lymph node dissection?

They may require removal or sampling to assess the extent of lymphatic tumor spread.

23. Which major vascular structures are at risk during common iliac lymph node dissection?

The common iliac arteries and veins.

24. Which nearby urinary structure must be identified and protected during common iliac lymph node dissection?

The ureter, which crosses the iliac vessels near the pelvic brim.

25. Which imaging technique is commonly used to evaluate enlarged common iliac lymph nodes?

Contrast-enhanced computed tomography of the abdomen and pelvis.
