摘要
目的:评价超声诊断囊性肾癌的价值。方法:回顾性分析上海交通大学医学院附属瑞金医院2002年1月至2009年6月期间27例囊性肾癌超声表现和手术后病理检查结果。结果:本组27例囊性肾癌患者经超声检出25例,声像图表现为混合回声(16例)、低回声(5例)、稍高回声(3例)及等回声(1例)4种类型,其中混合回声型居多,占64.00%(16/25),且肿瘤最大径在3.60～11.00cm。超声图像表现为后3种回声的肿瘤最大径均≤4.00cm,超声表现往往提示为肾脏实质性占位。所有患者均行彩色多普勒血流显像检查,部分肿瘤在其实性或分隔上可显示彩色血流信号;3例行超声造影,部分分隔和囊壁可见少许微泡灌注,提示此处有微血管存在。结论:超声对囊性肾癌具有较高的诊断价值,因而目前超声仍是囊性肾癌的一种主要诊断手段,结合超声造影﹑增强CT及其他影像学检查对诊断囊性肾癌可以起互补作用,有助于早期诊断、早期治疗。
Objective To evaluate the diagnostic value of ultrasonography in cystic renal cell carcinoma. Methods Results of uhrasound diagnosis and postoperative pathologic examination of 27 cases of cystic renal cell carcinoma admitted from Jan. 2002 to Jun. 2009 were analyzed retrospectively. Results Of the 27 cases, 25 cases were detected by uhrasonography. The ultrasonic imaging of cystic renal cell carcinoma could be divided into four types： mixed-echo, hypoeehoic, slightly hypereehoic, and isoechoic. The majority （16/25, 64.00%） were of the mixed-echo type, with a maximum length from 3.60 to 11.00 cm. The maximum length of other three types were all ≤ 4.00 era. On color Doppler uhrasonography, blood flow signals were detected in solid part or septum of the mass. Contrast-enhanced ultrasonography performed in 3 cases showed microbubble peffusion in cystic wall and septum, suggesting the existence of microvessels. Conclusions Ultrasonography is still a major diagnostic tool for cystic renal cell carcinoma and has a high diagnostic value. Uhrasonography has a complementary effect when combined with contrast enhanced CT and other imaging examinations in the early diagnosis and treatment of cystic renal cell carcinoma.
