Dr. Jill Wruble's TedX talk: Incidentalomas: What they are and why you should be concerned?
An incidentaloma is a tumor (-oma) found by coincidence (incidentally) without clinical symptoms or suspicion. Like other types of incidental findings, it is found during the course of examination and imaging for other reasons. It is a common occurrence: up to 7% of all patients over 60 may harbor a benign growth, often of the adrenal or thyroid gland, that is detected when diagnostic imaging is used for the analysis of unrelated symptoms. With the increase of "whole-body CT scanning" as part of health screening programs, the chance of finding incidentalomas is expected to increase. 37% of patients receiving whole-body CT scans may have abnormal findings that need further evaluation. Since many incidentally found lesions may never cause disease, there is a huge risk of overdiagnosis.
When faced with an unexpected finding on diagnostic imaging, the physician faces the challenge to prove that the lesion is indeed harmless. Often, more tests are required to determine the exact nature of an incidentaloma. (Wikipedia)
Dr. Jill Wruble is a New Haven radiologist who has a special interest in this area. Her TedX talk: Incidentalomas: What they are and why you should be concerned is a great introduction to this topic. She will be speaking at Williams College in April of 2016 (exact date not set).
