title: 75Se selenomethionine in the diagnosis of hepatocellular carcinoma. Report of a false positive scan.
abstract: A 74 year old man presented with cryptogenic liver cirrhosis and ascites. On 99Tcm sulphur colloid scanning he was found to have a filling defect in the right lobe of the liver which disappeared when the liver scan was repeated with 75Se selenomethionine. This lesion, initially thought to be a hepatoma, proved eventually at post mortem to be a hyperplastic hepatic nodule.
