Adrenal incidentaloma is the most common adrenal neoplasm encountered in clinical practice. The timely, accurate, and cost-effective evaluation and management of adrenal lesions found incidentally can be challenging for clinicians. Evaluation begins with biochemical screening and additional imaging. Management strategies vary by patient factors and tumor characteristics. Adrenalectomy is indicated for lesions that are hormonally active, larger than 4-5 cm, symptom-related, and have an imaging appearance that is atypical of a benign lesion.
