An MRI contrast angiography revealed 2 different ectopic kidneys with hila facing ventral aspect, one of which was in the middle of two iliac arteries in the pelvic region and the other localized at a higher spot adjacent to left main iliac artery and aorta (Figure 1).
MRI contrast angiography (3D FLASH) "volume rendering" image. Accessory artery originating from iliac bifurcation of left kidney (thick arrow) and 5 polar (capsular) arteries can be seen (arrow heads). Most superior polar artery originating from distal SMA, courses through lower pole of left kidney. A renal artery branching from right common iliac artery starting point, divides into 2 branches and reaches renal pelvis (bended arrow). No polar artery is seen in this kidney. The kidney in the mid level has 2 renal veins, and the left vein is joining with the left renal vein and opening into vena cava interior (thin arrow).

Mid level kidney had 2 renal arteries and left vein was joining with left renal artery and opening to vena cava inferior at a low level (Figure 2).
