Radiology of the adrenal incidentalomas. Review of the literature

Abstract

The term “adrenal incidentaloma” is a radiological term. Adrenal incidentalomas are adrenal tumors discovered in an imaging study that has been obtained for indications exclusive to adrenal conditions (Udelsman 2001; Linos 2003; Bulow et al. 2006; Anagnostis et al. 2009). This definition excludes patients undergoing imaging testing as part of staging and work-up for cancer (Grumbach et al. 2003; Anagnostis et al. 2009). Papierska et al. (2013) have added the prerequisite that the size of a tumor must be “greater than 1cm in diameter”, in order to be called incidentaloma. Although in the most cases these masses are non-hypersecreting and benign, they still represent an important clinical concern because of the risk of malignancy or hormone hyperfunction (Barzon et al. 2003). The adrenal tumors belong to the commonest incidental findings having been discovered (Kanagarajah et al. 2012). © 2017, De Gruyter Open Ltd. All rights reserved
