常规超声和超声造影检查诊断肝内胆管细胞癌

目的 探讨肝内胆管细胞癌(ICC)常规超声和超声造影(CEUS)表现。方法 本组纳入52例ICC患者,常规行超声和CEUS检查,组织病理学诊断。结果 灰阶超声表现为均匀低回声者23例(44.2%,不均匀低回声者22例(42.3%),稍高和高回声者7例(13.5%);彩色多普勒血流(CDFI)表现为0级11例(21.2%),血流1级9例(17.3%),血流2级28例(53.8%),血流3级4例(7.7%);在51例可分析的病例中,CEUS呈Ⅰ型快速整体均匀增强10例(19.6%),Ⅱ型快速不均匀增强41例(80.4%),其中Ⅱa型整体不均匀增强19例(37.3%),Ⅱb型树枝样增强9例(17.6%),Ⅱc型厚壁不规则环状增强6例(11.8%),Ⅱd型环状和树枝样增强7例(13.7%)。结论 CEUS检查ICC有特征性表现,对早期诊断具有识别作用。

Conventionaland contrast-enhanced ultrasonography manifestations of intrahepatic cholangiocarcinoma

Objective The aim of this study was to summarize the conventional and contrast-enhanced ultrasonography(CEUS)manifestations of intrahepatic cholangiocarcinoma(ICC).Methods 52 patients with ICC were recruited in our hospital,and all underwent conventional and CEUS check-up.Results The gray-scale ultrasonography showed than the tumors presented with uniform hypoechoic in 23 cases(44.2%),uneven hypoechoic in 22 cases(42.3%),slightly hyperechoic and hyperechoic in 7(13.5%);the color Doppler flow imaging showed that the blood supply of lesions was in grade 0 in 11 cases(21.2%),in grade 1 in 9 cases(17.3%),in grade 2 in 28 cases(53.8%),and in grade 3 in 4 cases(7.7%);out of 51 eligible cases of ICC,the CEUS demonstrated that the enhancement performance in arterial phase was in typeⅠ,e.g.rapid overall uniform enhancement,in 10 cases(19.6%),and in typeⅡ,e.g.rapid uneven enhancement,in 41 cases(80.4%),out of which,in subtypeⅡa,the overall uneven enhancement,in 19 cases(37.3%),in subtypeⅡb,the dendritic enhancement,in 9(17.6%),in subtypeⅡc,thick-walled irregular ring-like enhancement,in 6(11.8%),and in subtypeⅡd,ring-like and dendritic enhancement,in 7(13.7%).Conclusion ICCs have some CEUS characteristic features,which might help for the early diagnosis.
