Background and Objectives：The purpose of this study is to determine the prevalence of abnormalities in the mastoid cavity and middle ear in a non-ENT population, and to correlate with clinical data. Subjects and Method：Cross-sectional study. We pro-spectively evaluated a total of 100 adults and 30 children undergoing MRI scan for suspected intracranial pathology from May The T2-weighted images were reviewed. The abnormalities found on MRI were divided into 1) mastoid cavity abnormality, and 2) middle ear abnormality. Al patients were asked to complete a questionnaire pertaining to symptoms of mastoid/middle ear path-ology and history of previous otitis media. Also, their ears were examined carefuly by otoscope or otomicroscope. Results：In both groups, most of abnormalities were foof the mastoid cavity were significantly correlated to clinically significant mastoid/midle ear diseases in adults. Conclusion：Incidental MRI abnormalities in mastoid cavity and middle ear detected in a non-ENT population were relatively uncomon, compared to incidental paranasal sinus abnormalities. However, clinicians should remember the posibility of the pathologies of adults.
