Clinical and Imaging Presentations are Associated with Function in Incidental Adrenocortical Adenomas - a Retrospective Cohort Study.

Age, sex, tumor size, and laterality were associated with ACA hormonal subtype and can guide diagnosis and management. Tumor growth was more common with younger age and longer follow-up. Unenhanced HU did not predict hormonal subtype or growth. Adrenalectomy for MACS and NFA was mainly performed in younger patients with larger tumor size, growth, and elevated post-dexamethasone cortisol.
