A case of duplication of inferior vena cava and turner syndrome: Is it a rare association?

Turner syndrome is one of the most common sex chromosome disorders with many anatomical abnormalities that affect physiological systems of human body. The most common cardiovascular anomalies in Turner syndrome are bicuspid aortic valve and coarctation of aorta. The venous anomalies include partial anomalous pulmonary venous return and persistent left sided Superior vena cava. Duplication of inferior vena cava (IVC) is rare in occurrence. On extensive literature search, no such case of IVC duplication in Turner syndrome is found. We, herein, report an incidental finding of IVC duplication in a known case of Turner syndrome. Any patient with Turner syndrome should be evaluated for additional venous anomalies.
