摘要
目的 探讨在肝肾间巨大肿块CT定位诊断中 ,用下腔静脉肝段推移征象区分肝脏与非肝脏来源占位病变的价值。资料与方法 经手术病理和临床证实的位于肝肾间区域 ,直径≥ 4cm肿块共 97例 ,均行CT增强扫描。其中肝脏来源 (试验组 ) 4 3例 ,非肝脏来源 (对照组 ) 54例。重点观察下腔静脉肝段推移的CT征象并用诊断试验评价该征象。结果 下腔静脉肝段推移征在试验组中的出现率为 86 .0 % (37/43) ;在对照组的出现率为 7.4% (4/54)。在推移方向的分布上 ,试验组和对照组没有显著差异 (χ2 =0 .0 3 ,P >0 .0 5)。下腔静脉肝段推移征诊断肝肾间巨大肿块来源于肝脏的敏感性 86 .0 % ,特异性 92 .6 % ,准确性 89.7%。结论 下腔静脉肝段推移征是诊断肝肾间巨大肿块来源于肝脏的有价值的CT征象。
Objective To evaluate IVC hepatic segment displacement (IVCHSD) sign on CT scan in determining the origin of huge mass in hepatorenal recess.Materials and Methods Enhanced CT scan was performed in 97 cases with pathologically proved mass (diameter≥4cm) located in hepatorenal recess. The mass was originated from the liver in 43 cases (study group), from extra hepatic structure in 54 cases (control group). The CT findings were analyzed, focusing on the IVCHSD sign.Results The incidence of IVCHSD sign in study and control group was 86.0% (37/43) and 7.4% (4/54), respectively. No significant difference in displacement direction between two groups was found (χ 2=0.03, P>0.05). The sensitivity, specificity and accuracy of IVCHSD sign for establishing the hepatic origin of the mass was 86.0%, 92.6% and 89.7%, respectively. Conclusion IVCHSD sign is a valuable CT sign in identifying the hepatic origin of huge mass located in hepatorenal recess.
