Intrahepatic venous continuation associated with inferior vena cava hypoplasia: evaluation with sonography, MR imaging and MR angiography.
A 17-year-old Asian girl was admitted to our hospital because of acute onset of abdominal pain. Abdominal imaging work-up revealed an unusual pattern of congenital vascular anomalies, including a hypoplastic IVC and large intrahepatic venous collaterals along with an atypical, accessory hepatic vein. Congenital or acquired abnormalities of the inferior vena cava (IVC) can lead to formation of collateral pathways that help bypass the blood flow obstacle.
