THE EVALUATION OF INCIDENTALLY DISCOVERED ADRENAL MASSES.

Abstract

OBJECTIVE\nThe objective of this Disease State Clinical Review is to provide clinicians with a practical approach to the evaluation of incidentally discovered adrenal masses.\n\n\nMETHODS\nA case-based clinical approach to the evaluation of adrenal masses is presented. Recommendations were developed using available prospective and randomized studies, cohort studies, cross-sectional studies, anecdotal observations, and expert opinions.\n\n\nRESULTS\nIncidentally discovered adrenal masses are common. The approach to the patient with an adrenal mass should involve assessment of malignant potential via imaging characteristics and adrenal hormone excess via clinical and biochemical features. The roles of biopsy, surgical or medical therapy, and longitudinal surveillance are also important to consider and are influenced by case-specific factors. Inappropriate or inadequate evaluations may put patients at increased risk for developing preventable adverse cardiometabolic outcomes or cancer.\n\n\nCONCLUSION\nIncidentally discovered adrenal masses require a multimodal assessment that involves interpretation of multiple imaging characteristics, dynamic and static hormonal measurements, and a nuanced approach to considering interventional diagnostics, treatments, and longitudinal surveillance. Herein, we review these evaluations and provide a practical approach for clinicians.\n\n\nABBREVIATIONS\nACTH = adrenocorticotropic hormone; CS = Cushing syndrome; CT = computed tomography; DHEAS = dehydroepiandrosterone sulfate; HU = Hounsfield units; MRI = magnetic resonance imaging; UFC = urinary free cortisol.
