A 45-year-old female with congenital intrahepatic portosystemic venous shunts with associated aneurysms. (a) US image shows an abnormal communication between the right hepatic vein (red arrow) and right portal vein through an aneurysm (blue arrow). Inferior vena cava (yellow arrow) is also seen. (b) Color Doppler US image demonstrates the communication of the right portal vein (red arrow) to the right hepatic vein (not shown) through an aneurysm (blue arrow) within segment VII of the liver. Color Doppler reveals flow within the right portal vein (red arrow) and the aneurysm (blue arrow). Inferior vena cava (yellow arrow) is also seen. Technique: curvilinear 1–4.5 MHz transducer performed on a Siemens Acuson S3000 ultrasound machine.
