Clinical, biochemical and radiological retrospective analysis in patients with adrenal incidentaloma

Abstract

Introduction: The aim of this study was to evaluate the epidemiological, demographic, clinical features, treatment approaches and survival of patients followed up for adrenal incidentaloma. Methods: The data of 46 patients who underwent treatment and follow-up for adrenal incidentaloma in Mersin University Health Research and Practice Hospital, Endocrinology Department between 2010 and 2014 were retrospectively analyzed. Results: The study group consisted of 13 male and 33 female patients. The mean age was 54.09 ± 10.7 years. The most common reason for admission was abdominal pain in 34.78% of patients, the most commonly diagnosed radiological method was 60.87% dynamic surrenal CT, and the most common localization was right surrenal gland. The mean diameter of the mass was 26.8±16.5 mm. The prevalence of hypertension was 50%, obesity was 47.8%, type 2 diabetes was 21.7%, osteoporosis was 42.8% and metabolic syndrome was 41.3%. According to the results of hormonal evaluation, 82.61% of the patients had dysfunctional adrenal adenoma (FAA), 15.21% of them had subclinical Cushing syndrome (SCS) and 2.1% of them had aldesteronoma. Myelolipoma, benign pheochromocytoma and adrenocortical adenoma were diagnosed in 8 patients who underwent adrenalectomy. One patient died due to liver failure. No hormonal activation and lesion size growth was detected in the follow-up of the patients. Conclusion: Because of the different pathological and radiological features of AI, it is important to evaluate demographic, etiological, clinical, laboratory and radiological data as a whole in treatment and follow-up.
