Background and aim: Adrenal incidentalomas are discovered incidentally. Incidence has been increasing proportionally to the use of radiographic imaging. We aimed to evaluate patients with adrenal incidentalomas demographically.

Subjects and methods: This study was performed between January 2010 and February 2013. Total 320 patients (55.4±11.7 years) with adrenal incidentaloma (86 (26.8%) male (55.2±11.6 years) and 234 (73.1%) female (56.2±12.3 years) were included. All data were shown as mean±S.D.. χ2 and Pearson’s correlation mathods was used and values P<0.05 as accepted statistical meaningful.

Results: Majority of cases was in 6th and 7th decades in both gender. First diagnostic procedure was ultrasound in 24.8%, MRI in 14.9% and CT in 60.2%. Cause of radiologic imaging was renal and liver disorders in 71.2%, thorax pathology in 20.4%. Location of incidentaloma of all patients was 48.4% in right side, 41.8% in left side and 9.68% bilateral. Whereas location of incidentaloma of male patients 53.4% in right side (n: 46), 34.8% in left side (n: 30) and 11.6% bilateral (n: 10). In female patients 46.5% in right side (n: 109), 44.4% in left side (104) and 13.2% bilateral (n: 31). Mean mass size of male patients (33.9±22.9 mm) was higher than female patients (28.6±20.0 mm) (P=0.002). All cases were divided into three groups in according to tumor sizes <40 mm, 40–60 mm and >60 mm. In male patients number of mass size between 40–60 mm (n: 17, 19.5%) and >60 mm (n: 8, 9.1%) was higher than female patients (respectively n: 18, 7.6% and n: 12, 5.1%). Mean mass size of <40 age patients, was significantly larger than other (40–65 and >65 years) patients (P=0.003).

Conclusions: Adrenal incidentalomas has a clear female predominance. Most common diagnostic procedure of adrenal incidentaloma was CT. Main cause of radiologic imaging was renal and liver disorders. Mass size of male patients was higher than females.
