Abstract
60cases with filling defects on the liver scintigrams were studied with peritoneoscopy. 17 cases (28.3%) were proved to have space occupping masses in the liver in accordancewith filling defects on the liver scintigrams. But, 37 cases(61.7%) could not been foundany space occupping masses in the liver, as it were, false positive(Table 1). The causes for false positive diagnoses were:(1)the gall bladder fossa and portahepatis (15 cases);(2) atrophy of the liver (7 cases); (3) liver cirrhosis (6 cases); (4)adhesion of the urdersurface of the liver(3 cases);(5)extrinsic pressure defects of tumor(2cases);(6)intrahepatic biliary duct dilatation(2 cases);(7)malformation of the liver(1case);(8)radiation induced hepatic injury(1 case)(Table 2). The instructive 6 caseswith false positive hepatic scans were reported(Fivure 1-14). Since a filling defect on the liver scintigram may appear in a variety of clinical condi-tions, peritoneoscopy is important for the establishment of a correct diagnosis.
