Multisegmental anomaly of the inferior vena cava with thrombosis of the left inferior vena cava

We present a rare case of an extensive venous thrombosis associated with a multisegmental anomaly of the inferior vena cava (IVC), double IVCs, a hypoplastic right IVC, an aneurysm arising at the distal portion of the right IVC, and a severe stenosis between the prerenal and the hepatic segments of the IVC.
