Incidental adrenal masses - A primary care approach.

BACKGROUND

The common use of cross-sectional imaging for the investigation of abdominal and thoracic illness has resulted in the rise of the incidentally identified adrenal mass, or incidentaloma, which presents a diagnostic and management dilemma for the primary care physician.

OBJECTIVE

This article provides a framework for the investigation and management of incidental adrenal masses.

DISCUSSION: Adrenal incidentalomas are found in approximately 3-4% of abdominal computed tomography (CT) scans. It is important to evaluate these incidental adrenal lesions to determine what treatment, if any, is needed and when specialist referral may be necessary. In particular, incidentalomas must be evaluated in regard to their functional status and malignant potential, as lesions can range from being indolent, benign and non-functioning tumours that can simply be observed, to aggressive and hormonally active malignant lesions that require urgent surgical intervention.
