[Hormonal evaluation of adrenal incidentalomas]

Imaging technological advances and widespread use of abdominal imaging have led to the identification of an increasing number of adrenal incidentalomas in the last decades. Causes of these adrenal masses are multiple, but the most common etiology is the non-functional adenoma. Although in most cases, these masses are benign and non-functional, clinicians have to perform biochemical testing for subclinical cushing's syndrome, pheochromocytoma or primary hyperaldosteronism. This screening is essential for their etiological diagnosis and therapeutic management. We report in this article the biological approach to detect secretory activity of adrenal incidentalomas and the diagnostic accuracy of the biochemical tests used.
