Intrahepatic spontaneous portosystemic venous shunt: value of color and power Doppler sonography.

Spontaneous portosystemic venous shunts (SPVSs) within the hepatic parenchyma are rare. Fewer than 50 cases have been reported, and most of them were diagnosed by angiography. We present a case of SPVS diagnosed by color Doppler sonography in a 5-year-old boy admitted for bleeding due to rupture of esophageal varices. Conventional color and power Doppler sonography as well as CT showed a large shunt between the posterior branch of the right portal vein and the inferior vena cava. We believe that accurate diagnosis and follow-up of SPVS can be done with color Doppler sonography without resorting to angiography.
