超声在囊性肾癌的诊断与鉴别诊断价值及误诊原因分析

The Characteristics and Misdiagnosis Causes of Ultrasound in Diagnosis of Cystic Renal Cell Carcinoma

目的探讨超声在囊性肾癌(cystic renal cell carcinoma,CRCC)诊断与鉴别诊断中的价值及误诊原因分析。方法回顾性分析2011年1月至2016年12月收治并经手术及病理证实为囊性肾癌的23例患者的临床及超声检查资料。结果超声检查结果显示23例肿瘤多囊性病变15例,单囊性病变8例。19例诊断为CRCC,4例误诊为肾囊肿,误诊率17.39%。2例囊壁薄而规整,超声误诊为肾囊肿,2例囊壁及多数分隔较规整,超声误诊为多房性肾囊肿。结论超声检查可为临床早期诊断CRCC提供重要影像学依据。

Objective To explore the value of ultrasound indiagnosis and differential diagnosis and misdiagnosis causes of cystic renal cell careinomas（CRCC）.Methods Sonographic features of 23 patients by surgery and pathology from January 2011 to December 2016 were retrospectively analyzed.Results The ultrasound examination results showed that 15 patients with multicystic lesion,8 patients with single cystic lesion in the 23 patients.A total of 19 patients were diagnosed as having CRCC,and 4 patients（17.39%）were misdiagnosed as having renal cyst.The cystic wall were regular in 2 eases which were misdiagnosed as cyst of kindey,,and the septum was regular in 2 case which was misdiagnosed as multilocular cyst of kindey.Conclusion Ultrasonography can provide important evidences for early diagnosis of CRCC.
