Duplicated infrarenal IVC with azygous continuation of left IVC: Pre-operative CT and 3-D reconstruction image findings

Duplication of IVC (inferior vena cava) is rare. The embryogenesis of IVC is a complicated process. Disruption of this process in various stages can result in the majority of IVC abnormalities. We herein present a case of a 76-year-old man who had a preoperative computed tomography (CT) examination to evaluate for a renal mass in his left kidney. An incidental finding of a duplicated infrarenal IVC with azygous continuation of left IVC was noted. Three-dimensional CT reconstruction images enhanced visualization of the anatomical anomalies. Awareness of the IVC anomalies can help clinicians avoid diagnostic pitfalls and reduce complication of abdominal surgeries.
