Duplication of the inferior vena cava with azygos continuation, retroaortic left renal vein and iliac vein variations.
We present a rare complex variation of the inferior vena cava and internal iliac veins demonstrated by a multidetector computed tomography. It was shown that patient had double inferior vena cava with azygos continuation of the right inferior vena cava, retroaortic left renal vein and the left and right internal iliac veins converged and drained to the right external iliac vein through a common trunk. These variations of the inferior vena cava and iliac veins are important in the retroperitoneal surgery. We present multidetector computed tomography findings of this complex variation (Fig. 3, Ref. 12).
