Left gonadal vein is enlarged, and a collateral veinous pathway links the left renal vein to the splenic vein.
Case Discussion
The patient did not notice any macroscopic hematuria. No other obvious cause for intermittent chronic left flank pain in this athletic patient.
The differential diagnoses include left renal vein thrombosis or anatomical variants such as retroaortic or circumaortic left renal vein.
Duodenal compression can be associated, which is not the case here.
