Adrenalectomy Versus Follow-up in Patients With Subclinical Cushings Syndrome
Adrenalectomy Versus Follow-up in Patients With Mild Hypercortisolism: a Prospective Randomized Controlled Trial

Incidental findings of adrenal tumours,"incidentalomas", occur in 1-5 % in the general population and 10-25 % of these patients will exhibit biochemical mild hypercortisolism. Although the patients do not have clinical signs of classical Cushing's syndrome, they have an increased risk for hypertension, dyslipidemia, diabetes mellitus, osteoporosis and obesity.

The hypothesis of the study is, that surgery of the adrenal adenoma responsible for the increased secretion of cortisol, will in part cure or ameliorate the metabolic syndrome.
