[Brain Tumor Findings in Brain Check-up and Clinical Management: A Retrospective Analysis]

This retrospective study investigated the frequency, types, clinical courses, and management strategies of incidentally discovered brain tumors in 2,281 asymptomatic individuals (mean age; 59.0 years, 48.8% women) who underwent brain checkups at our institution between 2018 and 2025. Brain tumors were detected in 16 patients (detection rate; 0.7%), consistent with the results of large-scale neuroimaging studies in healthy populations. However, because of age variability in previous studies, we focused on data from cohorts with an average age >50 years for comparative analysis. The most common types are meningiomas and pituitary tumors. Here, we present representative cases of these tumors and discuss the decision-making process between active treatment and observation, considering tumor characteristics, location, and potential for symptom development. Appropriate diagnostic evaluation and multidisciplinary management can lead to early detection and timely intervention, thereby improving prognosis and quality of life.
