Incidentally detected renal masses are common, and can require follow-up. Recommendations from the 2017 ACR white paper on incidental renal masses suggests that small homogeneous masses measuring less than 20 Hounsfield units are probably benign, and do not require further characterization. However, new evidence from a multi-institutional study in AJR suggests that this cutoff should be raised to at least 30 Hounsfield units. In this episode, Matthew Petterson, MD discusses the new evidence.
