Surgical indications

Some investigators suggest that when a solitary, unilateral macroadenoma (>1 cm) is detected on a CT scan in a young patient in the setting of unequivocal aldosteronism, unilateral adrenalectomy is indicated. However, because of the age-dependent risk that a solitary, unilateral adrenal macroadenoma may be a nonfunctioning adenoma, some experts believe that adrenal vein sampling [22] should be performed in patients older than 40 years.
