Objective: Adrenal incidentaloma are bulks which are stated incidentally by imagining methods or in abdominal laparotomy when there is no suspicion of any disease in adrenal gland. With increase in using abdominal ultrasonography and BT, the frequency of determining adrenal incidentaloma also increases. In this study, we aimed to examine demographical features and insulin resistance in patients with non functioning adrenal incidentaloma (NFAI). Methods: 30 (20 female–10 male) patients, who followed due to NFAI at Dicle University Medical Faculty Department of Endocrinology between years of 2007-2013, and age, BMI matched 66 healthy subjects were included in the study. Results of physical examination, USG and BT were recorded from patients’ files. All patients were underwent following analyses for excluding a functioning adrenal mass, overnight dexamethasone suppression test, 24 hour urinary metanephrine and normetanephrine, plasma aldosterone/ renin activity ratio. Insulin resistance was calculated in accordance with homeostatic model assessment- insulin resistance formula. Results: The average of age was 45.9 ± 10.9 years and body mass ındex (BMI) 28.5 ± 5.8. There were no significantly difference in terms of age, gender and BMI between groups. Fasting blood glucose and insulin resistance were significantly higher in patients with non-functional adrenal incidentaloma than control group (p=0.022, p=0.005i respectively). No significant difference was found between groups, in terms of LDL, HDL and triglyceride levels. Conclusion: patients with NFAI are more prone to have insulin resistance and hyperglycemia. Thus, clinicians should evaluate those patients with NFAI, in terms of metabolic parameters.
