目的:探讨囊性肾癌的超声表现及其诊断价值。方法:20例囊性肾癌病例术前均行超声检查,并与CT对照。结果:20例囊性肾癌均经手术和病理证实,其中左侧13例、右侧7例,超声和CT均全部检出。常规超声病灶表现为单房或多房囊肿4例、瘤内分隔9例、瘤内结节5例、类实质回声2例。彩色多普勒超声发现瘤内血流17例,其中测及动脉频谱16例,阻力指数平均为0.66。CT表现为病灶增强后早期不均匀强化17例,其中5例分隔强化、4例结节强化。常规超声联合彩色多普勒超声诊断准确率为85%,CT诊断准确率为80%。结论:常规超声联合彩色多普勒超声和增强CT对囊性肾癌的诊断有重要价值。
Objective: To investigate the ultrasound findings and its diagnostic value of cystic renal cell carcinoma. Methods: 20 cases of cystic renal cell carcinoma were examined by ultrasound before operation and compared with CT. Results: All the 20 cases of cystic renal cell carcinoma were confirmed by operation and pathology. Among them, 13 cases on the left and 7 cases on the right were all detected by ultrasound and CT. Conventional ultrasound lesions showed single or multiple cysts in 4 cases, 9 cases of tumor separation, nodules in 5 cases, 2 cases of type of real echo. Intra-tumor blood flow was found in 17 cases by color Doppler ultrasound, of which 16 cases were measured and the arterial spectrum was measured. The average resistance index was 0.66. Seventeen cases were characterized by early enhancement of lesion enhancement after CT enhancement. Among them, 5 cases were separated and enhanced, while 4 cases were enhanced with nodules. Conventional ultrasound combined with color Doppler ultrasound diagnostic accuracy was 85%, CT diagnostic accuracy was 80%. Conclusion: Conventional ultrasound combined with color Doppler ultrasound and enhanced CT is of great value in the diagnosis of cystic renal cell carcinoma.
