目的探讨不同病理类型肾脏肿瘤的造影特点,评价超声造影诊断肾脏肿瘤的应用价值。方法对13例超声诊断为肾脏占位病变或可疑肾脏占位病变的患者应用新型声学造影剂声诺维进行超声造影检查。结果13例肾脏肿瘤超声诊断中,14.8%呈强回声(与肾窦回声相等或更强),33.3%强弱回声混杂,40.7%中等回声(与肝相似),3.7%中等偏低回声(介于肝肾回声之间),7.4%弱回声(与肾实质相同),30%肿馏内部回声均不均匀,瘸内见到智状结构,36.7%有中心性或偏心性液化囊变,20%肿块内有斑点状钙化,60%肿增周边有弱回声晕。肿瘤边界多数清楚,少数不清,1例肾癌术后局部复发,表现肾窝内形状不规则不均匀的低回声团块。结论超声造影对肾脏肿瘤的诊断和鉴别诊断具有一定的实用价值。
Objective To investigate the angiographic features of different pathological types of renal tumors and evaluate the value of contrast-enhanced ultrasound in the diagnosis of renal tumors. Methods Thirteen patients with sonography or suspicious renal space-occupying ultrasonography were enrolled in this study. Results In 13 cases of renal tumors, 14.8% showed strong echoes (equal to or stronger than the echo of the renal sinus), 33.3% of strong and weak echoes, 40.7% of moderate echoes (similar to the liver), and 3.7% of moderate and low echoes Echogenicity between the liver and kidney), 7.4% weak echo (same as renal parenchyma), 30% internal echogenicity of the swollen is not uniform, lameness see Zhiguo structure, 36.7% have central or eccentric cystic degeneration, 20 % Mass speckled calcification, 60% swollen peripheral weak echo halo. Most tumor boundaries clear, a small number of unclear, 1 case of local recurrence of renal cell carcinoma, the performance irregular renal irregular shape of the hypoechoic mass. Conclusion Contrast-enhanced ultrasound has some practical value in the diagnosis and differential diagnosis of renal tumors.
