A member asked:
What is an incidental retroaortic left renal vein? the key term here would be "incidental" as it appears that something caused it to be retroaortic
2 doctors weighed in across 2 answers
Incidental: Means it was noticed but does not have an implication on the other findings or symptoms of the patient, basically it is unusual but harmless.

Normal finding.: The left renal vein which comes off the inferior vena cava normally crosses in front of the aorta and not behind it in the usual anatomy. In about 5% of people the left renal vein will pass behind the aorta (retro aortic). This is a normal anatomic variation and normal for that person. It is usually identified on ct.
