A Proposal for Nomenclature Revision of Nonfunctioning Adrenal Incidentalomas as Adrenal Lesions of Undetermined Secretion of Adrenal Steroids (ALUSAS)

Publication Date Sep 1, 2022


In this commentary we propose a change of the nomenclature of non-functioning adrenal incidentalomas (NFAI) to adrenal lesions of undetermined secretion of adrenal steroids (ALUSAS) since there are mounting evidence suggesting that a substantial proportion of so-called NFAIs do actually secrete steroids in excess. In fact, it is known that some NFAIs develop ACS over time. In the commentary we justify the change of term by summarizing the evidence that shows that NFAIs present a higher cardiometabolic risk than the general population, and the metabolomics studies in which an increase in cortisol metabolites is observed in patients with NFAI.
