Incidental medical findings are previously undiagnosed medical or psychiatric conditions that are discovered unintentionally and during evaluation for a medical or psychiatric condition. Such findings may occur in a variety of settings, including routine medical care, during biomedical research, during post-mortem autopsy, or during genetic testing. Incidental imaging finding An incidentaloma is a tumor found by coincidence which is often benign and does not cause any clinically significant symptoms; however a small percentage do turn out to be malignant. Incidentalomas are common, with up to 7% of all patients over 60 harboring a benign growth, often of the adrenal gland, which is detected when diagnostic imaging is used for the analysis of unrelated symptoms. As 37% of patients receiving whole-body CT scan may have abnormal findings that need further evaluation and with the increase of "whole-body CT scanning" as part of health screening programs, the chance of finding incidentalomas is expected to increase. Incidental findings in neuroimaging are common, with the prevalence of neoplastic incidental brain findings increasing with age. Even in healthy subjects acting as controls in research incidental findings are not rare. As most neuroimaging studies are performed in adults, less is known about the prevalence incidental findings in children. A study in 2017 in nearly 4000 children between 8 and 12 reported that approximately 1 in 200 children showed asymptomatic incidental findings that required clinical follow-up. Pituitary adenomas are tumors that occur in the pituitary gland, and account for about 15% of intracranial neoplasms. They often remain undiagnosed, and are often an incidental finding during autopsy. Microadenomas (
