Adrenals

Abstract

Adrenal masses are often incidentally detected in imaging studies acquired for indications unrelated to suspected adrenal disease (Young Jr 2007). With rising numbers of imaging studies, the incidence of incidentalomas of the adrenal gland increases (Kaltsas et al. 2012; Lee and Lee 2014; Elsayes et al. 2016). Adrenal lesions can be classified as malignant or benign lesions with or without hormonal hypersecretion, which can be assessed clinically or biochemically (Young Jr 2007; Boland et al. 2008). Non-hypersecreting adrenal tumors are more common and comprise both malign and benign lesions (Young Jr 2007; Elsayes et al. 2016; Boland et al. 2008). Owed to the high number of incidental findings, accurate lesion characterization is mandatory (Blake et al. 2010; Korobkin 2000; Mayo-Smith et al. 2001; Slattery et al. 2006; Angeli et al. 1997) (Fig. 1).
