目的 :应用二维及彩色多普勒超声诊断胆管细胞型肝癌 ( CC)。方法 :分析 17例经病理证实的 CC的超声图像特点 ,其中男 8例 ,女 9例 ,平均年龄 5 6岁。结果 :1CC多表现为肝内单发实性肿块 ,形状不规则 ,边界不清楚 ;2 CC占位效应不明显 ,位于肝表面可见“脐凹”,并可包绕或跨越 Glisson系统生长 ;3内部多为均匀低回声 ,边缘回声略强 ;4CDFI检查显示肿块内血流信号稀少或见不到。本组病例阳性预期值 88% ,诊断准确率 82 %。结论 :超声诊断 CC有较高的应用价值 ,其特异性优于 CT检查
Objective: To evaluate cholangiocarcinoma (CC) by two-dimensional and color Doppler sonography. Methods: 17 cases of pathologically confirmed CC ultrasound image features, including 8 males and 9 females, with an average age of 5,6 years. Results: 1CC mostly manifested as single intrahepatic solid mass with irregular shape and unclear boundary; 2 CC occupancy effect was not obvious, located on the liver surface can be seen “umbilical concave”, and can be wrapped around or across the Glisson system; 3 Internal mostly low hypoechoic, slightly stronger edge echoes; 4CDFI examination showed that the blood flow signal within the tumor sparse or not seen. The positive predictive value of this group of patients 88%, diagnostic accuracy 82%. Conclusion: Ultrasound diagnosis of CC has a higher value, its specificity is better than CT examination
