Advanced Internal Iliac Nodes Quiz

Q1. Why are internal iliac nodes important during pelvic lymph node dissection?

• They surround the coronary arteries
• They are closely related to pelvic vessels and drain multiple viscera
• They are located in the posterior neck
• They lie within the humerus

Q2. Which nerve is especially relevant when nodal dissection extends into the obturator region?

• Phrenic nerve
• Obturator nerve
• Median nerve
• Radial nerve

Q3. Why can prostate cancer involve internal iliac lymph nodes?

• The prostate drains only to axillary nodes
• Prostatic lymph drains directly into the portal vein
• Prostatic lymphatics include pathways to internal iliac nodes
• The prostate has no lymphatic vessels

Q4. Why can cervical cancer spread to several different pelvic nodal groups?

• The cervix has no regional lymphatic drainage
• The cervix has multiple communicating pelvic lymphatic pathways
• The cervix drains only to superficial inguinal nodes
• All cervical lymph enters the inferior vena cava directly

Q5. Which feature helps distinguish internal iliac nodes from external iliac nodes anatomically?

• They follow different iliac vascular territories
• Both groups occupy exactly the same vascular chain
• Internal iliac nodes are in the neck
• External iliac nodes are located in the thorax

Q6. Why can enlarged internal iliac nodes be significant on pelvic imaging?

• They exclusively indicate scalp infection
• They always indicate disease of the hand
• They enlarge normally after every meal
• They may indicate disease in structures draining to the internal iliac territory

Q7. How do internal iliac nodes participate in lymphatic spread beyond the pelvis?

• They empty directly into the portal vein
• They drain through popliteal nodes toward axillary nodes
• They drain through cervical nodes into the mediastinum
• They drain through common iliac nodes toward lumbar nodes

Q8. Why is the branching pattern of the internal iliac artery relevant to nodal anatomy?

• All internal iliac nodes lie within the bladder lumen
• Lymph nodes are located only inside arteries
• Arterial branching has no anatomical relationship to pelvic lymphatics
• Nodal pathways are organized around variable internal iliac vascular branches

Q9. Why is precise knowledge of internal iliac nodal anatomy important in oncologic surgery?

• It supports complete nodal assessment while protecting nearby structures
• It removes the need to identify pelvic vessels
• It determines the arterial oxygen content
• It guarantees that metastasis cannot recur

Q10. Which statement best integrates internal iliac lymph node anatomy?

• Lower limb nodes confined to the popliteal fossa
• Pelvic nodal chains along internal iliac vessels that drain toward common iliac nodes
• Thoracic nodes surrounding the pulmonary arteries
• Cervical nodes draining directly to the portal vein
