O’Sullivan JW, et al. - Researchers conducted an umbrella review of systematic reviews and meta-analyses of observational studies describing the prevalence and outcomes of incidental imaging findings. For the purpose of this investigation, MEDLINE, EMBASE were searched up to August 2017. They identified 20 systematic reviews (240 primary studies) from 7098 references from the database search. Both in the prevalence of incidentalomas and in the prevalence of malignancy for specific organs, there was large variability across different imaging techniques. This umbrella review will help physicians and patients weigh up the upsides and downsides of requesting imaging scans, and will assist with management decisions after an incidentaloma diagnosis. The outcomes can underpin the creation of guidelines to assist these decisions.
