ABSTRACT
Objective To investigate the value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of small renal cell carcinoma (SRCC) and renal angiomyolipoma (AML) with minimal fat.Methods The images and data of conventional ultrasound (US) and CEUS were retrospectively reviewed in 47 cases of small renal cell carcinoma and 8 cases of AML with minimal fat (d < 30mm),which were confirmed by operation and pathologicall study,including 39 males and 16 females.The mean age of the patients was (54.8 ± 9.8) years old,ranged from 31 to 73 years old.The size,echo,boundary and color flow signals of renal lesions were observed by conventional US.Then the modality and phases of enhancement were observed,including the arrival time,the peak time,the washout time and the appearance of internal structures.Results On contrast-enhanced sonography,fast wash-in and wash-off were observed in most of SRCC,while slow wash-off were observed in most of RAML with minimal fat.The statistically significant differences were found between SRCC and RAML with minimal fat in the values of TFP (time a to peak) and PI (peak-intensity).The occurrence of round pseudo-capsule and contrast-enhancement characteristics in SRCC was far more often than RAML with minimal fat.Conclusions Contrast-enhanced sonography combined with time-intensity analysis provides more useful information for the diagnosis of SRCC and AML with minimal fat.
