ABSTRACT
Objective To describe CT manifestations of intrahepatic spontaneous portosystemic shunts(ISPS) of cirrhosis.Methods Spiral CT(SCT) scans and related clinical findings of 15 cirrhotic patients with ISPS were retrospectively reviewed.Results Three kinds of ISPS were showed :①Right posterior portal vein type was in 12 cases and showed tortuous intrahepatic tubular structures which were all in the posterior segment of the right lobe connecting the right posterior portal vein to the inferior vena cava(IVC) in the suprarenal region in all cases.②Hepatic venous type was in 2 cases,the portal vein communication with the hepatic vein in the liver.③Apex type was in 1 case,the vein arose from the apex of the liver and drains into the internal thoracic vein.Blood ammonia levels were elevated in all cases and symptoms associated with hepatic encephalopahty were present in 2 cases.Conclusion To deeply understand the ISPS,it is of benefit for differential diagnosis of focal hepatic lesions.
