Duplication of the IVC
Figure 1: Abdominal CT scan at the level of the kidneys showing two circular structures on either side of the slightly calcified aorta, which are both IVCs (White arrows). |
Figure 2: Coronal plane of the abdomen on CT scan at the level of the IVC showing a duplicate IVC as indicated by the white arrows.

Various congenital variations of the inferior vena cava (IVC) have been described. These include:
a. Duplication of the IVC
b. Azygous continuation of the IVC
c. Left sided IVC
In duplication of the IVC, there are both left and right sided IVC’s inferior to the renal veins, lying either side of the abdominal aorta. These continue on either side to inform the common iliac vein. The left sided IVC usually ends at the level of the left renal vein.
Although not seen in this case there may be asymmetry in size between the two IVC’s.
