title: [Incidentalomas of the adrenal glands. Personal cases and review of the literature].
abstract: BACKGROUND
  The growing use of sensitive non-invasive methods to image the abdomen such as ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI), have resulted in increasing recognition of adrenal incidentalomas.
  
  
  METHODS
  In this study, we report the clinical, endocrine and radiologic evaluation of 75 patients (50 women and 25 men, mean age 56 +/- 14 years) with adrenal incidentaloma (size 1 to 18 cm, mean 3 +/- 2.5 cm). None of the patients showed any symptoms or clinical signs that might indicate the existence of adrenal dysfunction. The patients underwent basal and dynamic evaluation of the hypothalamic-pituitary-adrenal axis, renin-angiotensin-aldosterone system, and adrenomedullary function. Moreover, CT and MRI scan and Iodo-cholesterol (NP-59) scintigraphy were performed.
  
  
  RESULTS
  The endocrine evaluation indicated 11 cases of pre-clinical Cushing's syndrome, 2 cases of pheochromocytoma and 62 not-functionally adrenal masses. On the basis of endocrine and morphologic data, 29 patients underwent surgical treatment: 20 adrenocortical adenoma, 2 pheochromocytomas, 2 not-cortisol-secreting adrenal carcinomas, 1 adrenal lymphoma, 1 adrenal metastasis, 1 myelolipoma, 1 hemorrhage and 1 pseudocystis.
  
  
  CONCLUSIONS
  In conclusion, patient with an incidentally discovered mass has to be investigated to detect malignancy and subtle hormonal overproduction, to select the cases for surgical treatment.
