Increasing Specificity of Recommendations for Renal Incidentalomas [critique of article by Corwin et al.]

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.
