Imaging incidental adrenal lesions.

ABSTRACT: Incidental adrenal masses are among the most common incidental lesions detected on cross-sectional imaging. The majority are benign lesions, adenomas and myelolipomas being the most common. Simple cross-sectional imaging techniques using CT and MRI permit the characterization of over 80%, thereby requiring no further imaging. The remaining lesions are considered indeterminate. These lesions consist of benign and malignant lesions sharing imaging features. Further imaging and management of these indeterminate lesions should be guided by close collaboration between different specialists in an MDT setting. Advanced imaging options include dedicated adrenal scintigraphy, positron emission tomography CT, biopsy and surveillance. Biochemical and hormonal evaluation is also important to identify hyperfunctioning adrenal lesions. This review focuses on imaging features of benign and malignant adrenal masses used for characterization and suggests an imaging pathway for indeterminate adrenal masses.

Project description:PurposeIncidental adrenal masses (IAMs) are common but rarely evaluated. To improve this, we developed a standardized radiology report recommendation template and investigated its implementation and effectiveness.MethodsWe prospectively studied implementation of a standardized IAM reporting template as part of an ongoing quality improvement initiative, which also included primary care provider (PCP) notifications and a straightforward clinical algorithm. Data were obtained via medical record review and a survey of radiologists. Outcomes included template adoption rates and acceptability (implementation measures), as well as the proportion of patients evaluated and time to follow-up (effectiveness outcomes).ResultsOf 4,995 imaging studies, 200 (4.0%) detected a new IAM. The standardized template was used in 54 reports (27.0%). All radiologists surveyed were aware of the template, and 91% affirmed that standardized recommendations are useful. Patients whose reports included the template were more likely to have PCP follow-up after IAM discovery compared with those with no template (53.7% versus 36.3%, P = .03). After adjusting for sex, current or prior malignancy, and provider ordering the initial imaging (PCP, other outpatient provider, or emergency department or inpatient provider), odds of PCP follow-up remained 2.0 times higher (95% confidence interval 1.02-3.9). Patients whose reports included the template had a shorter time to PCP follow-up (log-rank P = .018). PCPs ultimately placed orders for biochemical testing (35.2% versus 18.5%, P = .01), follow-up imaging (40.7% versus 23.3%, P = .02), and specialist referral (22.2% versus 4.8%, P < .01) for a higher proportion of patients who received the template compared with those who did not.ConclusionsUse of a standardized template to communicate IAM recommendations was associated with improved IAM evaluation. Our template demonstrated high acceptability, but additional strategies are necessary to optimize adoption.
