Adrenal incidentalomas seldom change: study

But the tumours may be associated with a greater risk of cardiometabolic problems

Adrenal masses found incidentally on imaging rarely change after diagnosis but may carry an increased risk for cardiometabolic conditions, a study shows.

Kidneys with adrenal glands

US and UK researchers reviewed 32 studies reporting outcomes on more than 4100 patients (mean age 60, 62% women) whose tumours had been found incidentally on imaging.

Tumours fell into two types: benign non-functioning adrenal tumours or adenomas causing mild autonomous cortisol excess.

Average tumour growth was only 2mm over 53 months, while
