Cushing's syndrome in women: age-related differences in etiology and clinical picture.

We have shown for the first time that women with CS ≥ 65 years of age more commonly have adrenal etiology. The initial presentation of CS also differs between age groups, where women < 45 years are likely to present with weight gain, while those ≥ 65 years are frequently diagnosed incidentally, when screening for hypercortisolism in the presence of an adrenal incidentaloma.
