Management algorithm for communication of renal mass results at abdominal CT. Recommendation is assigned to each renal mass finding as to whether it warrants critical result communication. Uncertain renal masses are masses that could be solid. Morphologic change includes renal masses that show new, enlarging, or more irregular areas of enhancement, calcification, septa, or progressive wall thickening. Asterisk indicates size increase in solid renal masses or masses that could be solid (uncertain) would prompt further evaluation. Size increase alone should not necessarily prompt additional testing of Bosniak IIF cystic masses, because benign cysts can grow.
