目的分析肾细胞癌(RCC)的超声表现及特征,评价超声对其的诊断价值。方法对2004年1月~11月经手术病理证实的25例肾细胞癌患者的超声声像图进行分析。结果肾细胞癌超声表现多为边界较清的均匀低回声及等回声团块,小肾癌(≤3cm)可表现为高回声或等高回声。肿块周边及内部血流信号多丰富,可测及低阻血流信号。结论随着超声新技术的应用,超声是早期发现肾细胞癌的较有效方法。
Objective To analyze the ultrasonographic features of renal cell carcinoma (RCC) and evaluate its diagnostic value by ultrasound. Methods Twenty-five patients with renal cell carcinoma confirmed by surgery and pathology from January 2004 to November were analyzed by sonography. Results Most of the renal cell carcinoma showed ultrasonographic features such as uniform hypoechoic echo and equal echo mass. Small renal cell carcinoma (≤3cm) showed hyperechoic or high echo. Mass peripheral and internal blood flow signal is more abundant, measurable and low resistance blood flow signal. Conclusion With the application of new ultrasound techniques, ultrasound is an effective method for early detection of renal cell carcinoma.
