In medical or research imaging, an incidental finding (commonly known as an “incidentaloma”) is an unanticipated finding which is not related to the original diagnostic inquiry. As with other types of incidental findings, they may represent a diagnostic, ethical, and philosophical dilemma because the significance is unclear. While some coincidental findings may lead to beneficial diagnoses (“a lucky find”), others may lead to overdiagnosis in the form of unnecessary testing and treatment.
