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34例经手术病理证实的肾细胞癌患者的超声声像图进行回顾性分析。结果肾细胞癌超声表现多为边界较清晰的均匀低回声及等回声团块,小肾癌(直径≤3 cm)可表现为高回声或等回声,肿块周边及内部血流信号丰富,可测及低阻血流信号。结论超声对肾细胞癌有很高的诊断价值,是早期发现肾细胞癌的首选检查方法。
Objective To analyze the ultrasonographic features and characteristics of renal cell carcinoma (RCC) and evaluate the diagnostic value of ultrasonography. Methods Retrospective analysis was performed on 34 cases of renal cell carcinoma confirmed by surgery and pathology. Results The manifestations of renal cell carcinoma were mostly clear hypoechoic and homogeneous echogenic masses. Small renal cell carcinoma (≤3 cm in diameter) showed hyperechoic or equal echogenicity, abundant peripheral and internal blood flow signals, measurable And low resistance blood flow signal. Conclusion Ultrasound has a high diagnostic value for renal cell carcinoma and is the first choice for detecting renal cell carcinoma.
