目的:探讨肾实质肿瘤的声像图表现与超声诊断价值。方法:分析88例肾实质肿块的二维、彩色多普勒声像图表现与病理结果对照。结果:肾实质肿块以肾癌和错构瘤最多见,分别占71.6％和12.5％。各组肾癌和错构瘤均以表现强回声或高回声为主的肿块多见。随肿块增大,液化区出现率,肾癌转移发生和检出率增高,肾癌组滋养和瘤内动脉检出率增高。结论:二维结合彩色多普勒超声检查能提高肾实质肿瘤诊断正确率,对于部分直径<3cm肿块鉴别诊断困难时应结合其它影像检查,必要时活检。
Objective: To investigate the sonography of renal parenchyma tumors and ultrasound diagnostic value. Methods: Two-dimensional and color Doppler sonographic findings of 88 cases of renal parenchyma were compared with pathological findings. Results: The majority of renal parenchymal masses were renal carcinoma and hamartoma, accounting for 71.6% and 12.5% respectively. Each group of renal cancer and hamartoma are characterized by strong echo or hyperechoic mass more common. With the increase of lumps, the incidence of liquefaction area, the incidence of renal cell carcinoma metastasis and the detection rate increased, and the detection rate of nodules and intratumoral arteries in renal cell carcinoma group increased. Conclusion: Two-dimensional color Doppler ultrasound can improve the accuracy of diagnosis of renal parenchymal tumors. For the differential diagnosis of partial diameter <3cm, other imaging examination should be combined with biopsy if necessary.
