Abstract:
Objective To investigate the feasibility of contrast-enhanced ultrasonography (CEUS) combined with Bosniak classification in diagnosis of cystic renal cell carcinoma (CRCC). Methods Routine and contrast-enhanced ultrasonic manifestations of 24 patients (24 lesions) of CRCC confirmed with operation and pathology were retrospectively analyzed. The number of septa, thickness of wall and septa, with or without solid nodules and blood supply were evaluated. Each tumor was categorized on CEUS images using the Bosniak classification system, and the diagnostic coincidence rate was calculated. Results On routine ultrasonographic images, there were 2 lesions without septa, 8 with a few septa and 14 with multiple septa, 5 lesions with septa and (or) wall thickness ≤1 mm and 19 lesions thickness ＞1 mm; solid nodules were shown in 7 lesions and the color flow was shown in 11 lesions. On CEUS images, there were 8 lesions with a few septa and 16 with multiple septa, 1 lesion with septa and (or) wall thickness ≤1 mm and 23 lesions thickness ＞1 mm; solid nodules were shown in 9 lesions, and the enhancement could be demonstrated in all the lesions. According to Bosniak classification system, CEUS demonstrated 15 grade Ⅲ and 9 grade Ⅳ lesions. The diagnostic coincidence rate of CEUS combined with Bosniak classification was 100%. Conclusion The blood supply and sophisticated internal structures of CRCC can be shown better with CEUS than routine ultrasonography. CEUS combined with Bosniak classification can be used for the diagnosis of CRCC.
