The primary outcome of the systematic review was the prevalence of IF on a CT scan. The team undertook a comprehensive literature search for studies including terms such as ‘incidentaloma’ without a restriction on the type of study design and which included those that were retrospective, cross-sectional or prospective in nature. In addition, the researchers also wanted to better understand more about the subsequent actions taken by a department once such findings had been uncovered. The US team sought to estimate how common radiologic IF were among patients visiting an emergency department and who underwent a CT scan. The overall prevalence of IF in non-trauma patients, is less clear and was the subject of the present study. Although the detection of IF does not affect or alter an emergency department clinician’s current diagnostic work-up, it is important that these observations are communicated to patients to enable, where appropriate, further tests and follow-up to be undertaken. However, the presence of incidental findings are not uncommon, especially among scans for trauma patients with one study revealing how these findings were present in 15% of trauma CT scans. ![]() ![]() The term ‘incidentaloma’ refers to an incidentally discovered mass or lesion, that is detected using imaging and which was performed for an unrelated reason. Incidental findings (IF) are detected in almost a third of all computed tomography (CT) scans undertaken with emergency departments according to the findings of a systematic review by a group of US researchers. A systemic review has revealed how incidental findings on a CT scan in emergency departments can be detected in nearly a third of patients
