Large spontaneous intrahepatic arterioportal fistula demonstrated by rapid sequential computed tomographic scan. Report of two cases.
A huge spontaneous intrahepatic arterioportal shunt with regurgitation through the portal vein trunk was demonstrated by computed tomography and confirmed by angiography in 2 patients with liver cirrhosis. Rapid sequential computed tomographic scanning was very useful in the diagnosis and follow-up after arterial embolization. Early visualization of the portal vein and increased attenuation in the ipsilateral lobe bearing the fistula were demonstrated in 1 case, and the same findings were also demonstrated by computed tomography and angiography in the other case.
