Anatomy of the Origin of the Gonadal Veins on CT

When searching for the right GV, the right anterolateral quadrant should be searched first, as much as 25 mm caudal to the right renal vein ostium. If unsuccessful, the inferior wall of the right renal vein within 2 cm of its origin should be interrogated. On the left side, the inferior wall of the left renal vein should be examined. If a left-sided IVC is found, the GV will join it directly.
