Swedish guidelines for the management of adrenal incidentalomas Adrenal incidentalomas are seen in about five percent of abdominal CT examinations, and in most cases represent non-hormone-producing adrenocortical adenomas, but hormone-producing or malignant lesions occur. Revised Swedish guidelines for the evaluation and management of adrenal incidentalomas based on recently published European guidelines are presented. The importance of a thorough radiological, clinical and biochemical initial evaluation is emphasized. Long-term biochemical follow-up is not recommended and use of CT contrast medium »washout« calculation is omitted. No radiological evaluation or follow-up indicated for adrenal incidentalomas <1 cm size. For patients with diagnosed lipid rich adenomas (≤ 10 HU) 1-4 cm in size no radiological follow-up is suggested after initial evaluation.
