My mom had a ct done and it revealed bilateral masses on her adrenal glands, what could this mean, my mom has copd, a-fib?

Adrenal mass: :Can be adenoma, myelolipoma, cyst, lipoma, pheochromocytoma, adrenal cancer, metastatic cancer, hyperplasia, and tuberculosis . More than half of are benign/ hyperfunctioning adenomas need evaluation . Pheochromocytomas are associated with hypertension. rarely could be a cancer but that is in less than half the cases. f/u w/doc
