Clinically silent adrenal masses (incidentaloma) are incidentally discovered lesions, when noninvasive imaging methods (USG, CT, MRI) are performed for reasons other than known or suspected adrenal disease. Most studies report on a prevalence of adrenal incidentaloma range between 1% and 10% in radiological series. Between 1994 and 1999 we observed in our Department 57 patients with incidentalomas of adrenal glands. After endocrinological evaluation silent Cushing's syndrome was found in 2 cases (3.5%). Fifty two patients were qualified for surgery. Adrenocortical adenoma was diagnosed in 73.1%; adrenocortical carcinoma in 7.7%; pheochromocytoma in 7.7% and less frequent adrenal lesions in 11.5%. All adrenal carcinomas and malignant pheochromocytomas (11.5%) were found in tumors with diameter over 4 cm.
