BERKELEY, CA (UroToday.com) - Extension of the renal cell carcinoma into adjacent fat can have significant impact on staging and treatment strategies. Cross-sectional imaging can reliably predict perinephric fat invasion during preoperative evaluation of RCC. In our study, CT was more sensitive and MRI was more specific for detection of perinephric fat invasion. Mixed (linear–nodular) pattern was associated with more accurate detection of fat involvement, and the chance of positive pathology report was 2.8 times higher. The negative predictive values (NPVs) of 90% for CT and 86% for MRI emphasize that, in most of the cases, perinephric fat infiltration is unlikely to be present on pathology if it is not detected on CT or MRI preoperatively.
