Increased mortality in patients with adrenal incidentalomas and autonomous cortisol secretion: a 13-year retrospective study from one center.

Patients with autonomous cortisol secretion had higher mortality than those with non-functioning AIs though cortisol levels post-DST as a continuous variable, age and tumour size were better predictor of mortality. Cardiovascular disease and osteoporosis medication seemed more prevalent in the possible and autonomous cortisol secretion groups, especially in the former.
