Incidental Findings
Explore general guidance on managing incidentally discovered masses.
An incidental finding, also known as an incidentaloma, may be defined as “an incidentally discovered mass or lesion, detected by CT, MRI or other imaging modality performed for an unrelated reason.”
An increase in cross-sectional imaging examinations over the past three decades has led to a marked increase in the number of imaging findings that are unrelated to the primary indication for the test.
Each incidental finding guidance document addresses the patient population in which the recommendations apply and provides context for interpretation of the recommendations.
You can explore all Incidental Findings content on the ACR® Guidance App.
