Multicenter Study
Adrenal incidentaloma: an overview of hormonal data from the National Italian Study Group.
Adrenal masses are more and more frequently detected by adrenal ultrasound, computed tomography or nuclear magnetic resonance carried out for a reason other than the suspicion of adrenal disease (incidentalomas). The findings of an incidentaloma still leaves many diagnostic and therapeutic questions open. We report the results of a multicentric retrospective evaluation of patients with adrenal incidentalomas, performed by a Study Group of the Italian Society of Endocrinology. ⋯ Post-ACTH 17-OH progesterone levels were elevated in 52% (62/118 patients) of non-functioning adenomas and in 2 of 4 carcinomas. Not enough data are yet available postoperatively. In summary, endocrine evaluation can lead to the identification of a nonnegligible number of cases of clinically unsuspected pheochromocytomas and subtle hypercortisolism (about 3.4 and 6.2%, respectively of all adrenal incidentalomas), while cases of primary subclinical aldosteronism are rarely found.
