With the term of incidental mass, any mass is identified, occasionally discovered with imaging techniques, in the absence of specific symptoms. In 1982, the term "incidentaloma" was introduced to indicate lesions detected on adrenal regions, found unexpectedly. The incidence percentages vary from 0.6%-3% in CT followed by other indications , to 10% and 25% in all patients who underwent an ultrasound, CT or MRI. An appropriate diagnostic protocol is mandatory to identify and to choose the proper treatment for the functioning lesions, as well as the malignant or potentially malignant lesions (1, 2). Incidentalomas with diameters under 1 cm seem to not have a pathologic significance, and are considered like manifestation of the gland involution in advanced-age subjects, and can remain unseen for a long time. The use of diagnostic imaging techniques has made it possible to identify these masses, even those of small size, in the course of diagnostic surveys done under various guidelines. The mass dimensions are a fundamental parameter used to distinguish benign lesions from malign ones (2, 3). Most Authors suspect malignity in masses above 5-6 cm, while considering those with a diameter under 3 cm to be benign. Whereas the rest remain undefined, thereby valued and treated according to criteria not perfectly established.
