Xu Yonghua Shi Jianmin Liu Xiaohong et,al. Radiology Department of Shanghai 8th People′s Hospital 200235  
Purpose:To discuss the diagnostic evaluation of CT findings in hepatic metastases.Materials and Methods:100 Cases were retrospectively analyzed including the morphology,density,number,specific features,size of pre and post enhancement,intrahepatic distribution and extrahepatic metastatic lesions by CT scanning.Results:More than 3 lesions were showed in each of 65 cases,2 for each of 10 cases,and only 1 in 25 cases.71 cases revealed lesions in right lobe of liver or majority so,11 cases showed the equality of distribution in left and right lobes and 18 cases with lesions in or majority in left lobe.3 cases with fatty liver showed lesions in high density for 2 and another showed isodensity,lesions of the rest all were showed low density.Among 206 metastatic lesions,125 showed their sizes smaller than the post enhanced ones (60 7%) and the other 81 seemed to be in equal size before and after enhancement (39 3%).The rates of occurrence for bull eye sign,cystic necrosis sign,fluid-fluid level sign and intratumoral calcification were 8%,3%,2%and 4% respectively.Extrahepatic metastases occurred in 18 cases during CT examination.Conclusion:The variable size of the lesions,diffuse multiplicity and low density central necrosis with marginal enhancement were the basic CT manifestations.CT contrast scanning should be crucial to evaluate the exact sign of the metastatic lesion.
