Overview

Incidentaloma is an adrenal mass discovered serendipitously. Because of increasing use of imaging techniques it is a common finding, being present in more than 1 % of adults. During work-up malignancy has to be ruled out. Classically imaging using CT or MRI is used. Recently PET-CT with FDG has been used more often as its sensitivity for diagnosis of malignancy is about 97 % and specificity 91 %. Hormonal evaluation should diagnose subclinical hypercortisolism. (Dexamethasone Suppression Test is the method of choice). Aldosterone and Renin should be measured only in patients with hypertension and catecholamines in tumours with higher native density than 10 HU. During follow-up repeated CT scan are needed only in selected patients and the need of routine biochemical follow-up has been questioned as well.

Key words:
adrenal adenoma – adrenal incidentaloma – hormonal tests – imaging – pheochromocytoma
