Intermediate Para-aortic Lymph Nodes Quiz

Q1. Which subgroup of lumbar nodes lies immediately lateral to the abdominal aorta?

• Pretracheal nodes
• Parasternal nodes
• Lateral aortic nodes
• Submental nodes

Q2. Why do testicular lymphatics ascend to para-aortic nodes instead of draining primarily to superficial inguinal nodes?

• The testes develop from the anterior abdominal skin
• The testes originate embryologically in the posterior abdominal wall
• The superficial inguinal nodes lack lymphatic vessels
• Testicular arteries arise from the femoral artery

Q3. Which vessels commonly guide ovarian lymphatics toward para-aortic nodes?

• Ovarian vessels
• Internal thoracic vessels
• Inferior epigastric vessels
• Middle meningeal vessels

Q4. Which renal hilar structures are followed by lymphatics toward lateral aortic nodes?

• Inferior mesenteric vein only
• Renal vessels
• Round ligament of the liver
• Cystic duct

Q5. Which adrenal lymphatic drainage pattern is most accurate?

• Exclusive drainage to superficial inguinal nodes
• No lymphatic drainage
• Exclusive drainage to axillary nodes
• Drainage to lumbar para-aortic nodes

Q6. What is the relationship between lumbar trunks and the cisterna chyli?

• They form the ureters
• Lumbar trunks terminate in the gallbladder
• They enter the portal vein directly
• Lumbar trunks commonly join the central lymphatic convergence near the cisterna chyli

Q7. Which lymph node chain receives lymph ascending from common iliac nodes?

• Axillary nodes
• Popliteal nodes
• Lumbar para-aortic nodes
• Deep cervical nodes

Q8. How are para-aortic nodes related to the inferior vena cava on the right side?

• They lie only within the vena caval lumen
• They occur only above the diaphragm
• They are separated from the great vessels by the peritoneal cavity
• They form part of a retroperitoneal nodal network around the aorta and vena cava

Q9. Which structure does NOT normally drain primarily to para-aortic nodes?

• Ovary
• Kidney
• Testis
• Scrotal skin

Q10. Which pathway correctly traces lymph from a testis toward the central lymphatic circulation?

• Testis, superficial inguinal nodes, axillary nodes, thoracic duct
• Testis, portal vein, liver, thoracic duct
• Testis, para-aortic nodes, lumbar trunk, cisterna chyli or thoracic duct
• Testis, renal pelvis, ureter, thoracic duct
