[Hypoplasia of the inferior vena cava with intrahepatic continuation. Color Doppler ultrasonography and MRI].

We report a rare case of inferior vena cava hypoplasia discovered fortuitously, with intra-hepatic venous shunts, explored only by color-doppler ultrasound and MRI. These noninvasive imaging tests demonstrated that the intra hepatic collateral pathway arose from an inferior (accessory) right hepatic vein and flowed into the right and middle hepatic veins. Due to these findings a cavography was avoided in this asymptomatic patient.
