## Background: In the tnm classification of renal cell carcinoma released in 1997, t1 tumors were defined as organ-confined tumors 7.0 cm or less in size, and t2 as those larger than 7.0 cm. the consideration of tumor size should be predicated on its prognostic value in predicting survival, because

β¦ Synopsis
The sonographic appearance of 37 renal cell carcinomas was reviewed with particular emphasis on the relationship between the echo pattern of tumor and tumor size. Small carcinomas tended to be solid and hypoechoic; seven lesions less than 5 cm in the largest dimension were either hypo- or isoechoic . The echogenicity level of the solid parts within the lesion, whether it was solid or mixed, tended to increase as the tumor grew. It is important to recognize that the sonographic appearance of renal cell carcinomas varies with the size of the tumor.
