This document discusses adrenal incidentalomas, which are clinically unapparent adrenal masses detected incidentally on imaging studies. Key points include: - Adrenal incidentalomas are found in 1-4% of abdominal imaging and increase in prevalence with age. - They require evaluation to determine if they are functioning or malignant. Hormonal and biochemical testing, as well as imaging, are used to classify the mass and guide management. - Surgical removal is recommended for masses greater than 4 cm, those with suspicious imaging features, functioning tumors, and tumors that increase in size on follow up imaging. Laparoscopic adrenalectomy is the standard approach when possible.
