BACKGROUND: Incidental adrenal masses (IAMs) occur in approximately 4% of patients undergoing abdominal CT scans for any indication. Hormonal evaluation is recommended for all IAMs. The purpose of this study was to identify the rate of IAMs in a screening population and to determine the adequacy of endocrine evaluation of newly identified IAMs based on established guidelines.
METHODS: This was a retrospective analysis of 6913 patients undergoing a non-contrast screening CT colonography at a single academic medical center between June 2004 and July 2012.
RESULTS: The prevalence of IAMs in this asymptomatic screening population was 2.1% (n = 148). Of those patients, 8.8% (n = 11) underwent some form of hormonal evaluation and only 6.4% (n = 8) patients had a "complete" workup. Cortisol, metanephrines, and an aldosterone-renin ratio were evaluated in 8.0%, 7.2%, and 4.0% of patients, respectively. Of the patients (n = 11) who underwent hormonal evaluation, 27.3% had functional masses and 36.4% underwent surgery. Of those who did not have hormonal evaluation, 42.1% (n = 48) had comorbidities that should have prompted hormonal evaluation based on established guidelines. Hormonal evaluation was not performed in 89.4% of patients with hypertension and 21.1% of patients with diabetes. 88.9% of patients on three or more antihypertensive medications did not undergo any hormonal evaluation.
CONCLUSIONS: Compliance with IAM workup guidelines is poor, which may result in missed diagnosis of functional adrenal masses. Establishment of a robust protocol and education on appropriate workup for IAMs is necessary for adequate hormonal evaluation.
