ABSTRACT
A 70-yr-old man diagnosed with situs inversus was hospitalized because of hepatic encephalopathy. Per rectal portal scintigraphy showed portal hypertension and a region with high radionuclide activity in the right lateral region of the abdomen. In percutaneous transhepatic portograms, a giant portacaval shunt was seen in the region with high radionuclide activity. After the portacaval shunt was obstructed surgically, the hepatic encephalopathy disappeared. In per rectal portal scintigraphy done 2 wk after surgery, the pattern was normal and the region with high radionuclide activity had disappeared.
