Duplication of Inferior vena cava (IVC) is rare variant and usually detected incidentally by imaging techniques for other reasons. The formation of Inferior vena cava is by the union of right and left common iliac veins posterior to right common iliac artery at the level of fifth lumbar vertebra. The present case describes the unusual formation and duplication of IVC which was encountered during routine dissection of male cadaver which was used to educate medical undergraduate students. Duplication of inferior vena cava on either side of the abdominal aorta up to the 2nd lumbar vertebra was observed. Inferior vena cava on the right side was formed by union of right common iliac vein with left internal iliac vein. Left external iliac vein continued as accessory venous channel of inferior vena cava on the left side of abdominal aorta. These types of variations may cause misdiagnosis, unwanted hemorrhage during retroperitoneal surgeries due to ligation.
