目的:探讨肾血管平滑肌脂肪瘤(RAML)超声诊断的价值。方法:对我院30例RAML患者采用超声诊断仪进行二维超声和多普勒超声诊断分析。结果:25例为单发,5例为多发;病变部位左侧13例,右侧13例,双侧4例,其中最小者1.0cm×1.5cm,最大者15cm×12cm;高回声型24例,低回声型2例,混合型回声4例;30个瘤体中有5个瘤体内未显示血流信号,肿瘤内部血流参数RI<0.620例,0.6～0.71例,>0.74例;动脉峰速≤55cm/s20例,>55cm/s5例。结论:二维超声与多普勒超声联合应用,可提高检出率,超声对该病的定位有重要价值,而最终定性诊断还应依靠病理组织学诊断。
Objective: To investigate the value of ultrasound in the diagnosis of renal angiomyolipoma (RAML). Methods: Thirty patients with RAML in our hospital were diagnosed by two-dimensional ultrasonography and Doppler ultrasonography with ultrasonic diagnostic apparatus. Results: 25 cases were solitary and 5 cases were multiple. There were 13 cases on the left side, 13 cases on the right side and 4 cases on both sides. The smallest one was 1.0cm × 1.5cm, the largest one was 15cm × 12cm. The hyperechoic type was 24 , 2 cases of hypoechoic type and 4 cases of mixed type echo. No signal of blood flow was found in 5 of the 30 tumors. RI (0.620, 0.6-0.71, 0.74) Speed ≤ 55cm / s20 cases,> 55cm / s5 cases. Conclusion: Two-dimensional ultrasound combined with Doppler ultrasound can improve the detection rate. Ultrasound has important value in the localization of the disease, and the final qualitative diagnosis should rely on histopathological diagnosis.
