Patient Data
Age: 20 years
Gender: Female
From the case:
Retroaortic left renal vein
Loading images...
Longitudinal
Prominent left renal vasculature is seen in the first image that would suggest renal venous congestion.
Second image shows left renal vein passing between the aorta anteriorly and a lumber vertebral body posteriorly. This course is seen at the normal level of the left renal vein (Type 1 RLRV).
Case Discussion
Key learning points:
- don't interpret the first image as hydronephrotic changes, the color and doppler study would be a great differentiating tool
- the second image is a classic ultrasound finding of a retroaortic left renal vein which is variant anatomy
