Case report. Circumaortic left renal vein

Although computed tomographic (CT) characteristics of the inferior vena cava may mimic lymphadenopathy, careful appraisal of the vascular anatomy can diagnose major vascular anomalies by noninvasive techniques, eliminating the need for angiography as well as alerting our surgical colleagues of the benign nature of this entity. We document the first case of circumaortic renal vein by CT, discuss the CT appearance, and review its clinical significance.
