Aim: The incidence of adrenal incidentaloma has increased recently due to increased magnetic resonance imaging (MRI), computed
tomography scans (CT) and ultrasonography (USG). In our study, we aimed to demonstrate our radiologic, hormonal and clinical
follow up of adrenal incidentaloma
Material and methods: We retrospectively reviewed 276 patients with adrenal incidentaloma and excluded 73 of them. We collected
the data of demographic findings, size, hormonal activity of the mass and malignancy.
Results: Between 2007-2016 we diagnosed 203 adrenal incidentaloma patients in our clinic. The mean size of the tumors was
22,7±10,8mm. 157 (77,3%) of them were non-functional. We diagnosed 21 (10,3%) tumors with autonomous cortisol secretion,
9 (4,4%) cushing syndrome, 5 (2,5%) pheochromocytoma, 9 (4,4%) primary aldosteronism, 2 (1%) adrenocortical carcinoma. We
suggested surgery to patients with 15 functional, 13 non-functional incidentaloma and 2 incidentaloma with suspicious malignancy.
21 cases preferred to undergo adrenalectomy and 12 of them had retroperitoneal laparoscopic adrenalectomy. During their routine
follow up there was not any change in size of the tumors (p:0,12).
Conclusion: The incidence of non-functional adrenal incidentolama (%77,3) was similar to the literature (4-5-6). There was not
any change in size of the tumors during 3,9 year follow up of the patients. Although we had limited number of patients, we showed
that radiologic evolvement contributes to differentiation of benign and malign lesions. By this way, we could follow patients more
conservatively.
