目的分析囊性肾恶性肿瘤的超声声像图表现及与病理基础,提高对此病的诊断率。方法对经手术病理证实的28例囊性肾癌患者的超声声像图进行回顾分析。结果 28例囊性肾恶性肿瘤中,肾细胞癌19例,肾盂移行细胞癌8例,肾集合管癌1例。超声诊断表现为单房囊肿型6例,多房囊肿型16例,附隔、附壁结节型5例,囊实混合型1例。其中囊壁和(或)分隔可见钙化斑7例。CDFI和(或)PDI在肿瘤周边、分隔及实性结节内检测到星点状、短条状或分支状血流信号23例。误诊3例,漏诊2例,诊断检出率92.8%(26/28),符合率82.1%(23/28)。结论囊性肾恶性肿瘤的超声声像图表现有一定特征性,可为临床早期治疗提供重要的参考依据。
Objective To analyze the ultrasonographic appearance and pathology of cystic renal malignancies and to improve the diagnosis rate of this disease. Methods 28 cases of cystic renal cell carcinoma confirmed by surgery and pathology were retrospectively analyzed. Results Of the 28 cases of cystic renal malignant tumors, 19 were renal cell carcinoma, 8 were renal pelvis transitional cell carcinoma and 1 was tubular aggregate carcinoma. Ultrasonographic manifestations of single cysts in 6 cases, 16 cases of multiple cysts, parietal, parietal nodules in 5 cases, cystic solid mixed type in 1 case. Including wall and (or) separation of visible calcified plaque in 7 cases. CDFI and / or PDI in peripheral tumor, separated and solid nodules were detected in the star-shaped, short or branched blood flow signal in 23 cases. 3 cases were misdiagnosed and 2 cases were missed. The detection rate was 92.8% (26/28) and the coincidence rate was 82.1% (23/28). Conclusion Ultrasound of cystic renal malignant tumors has some characteristic features of ultrasound, early clinical treatment may provide an important reference.
