I have a pituitary adenoma (16mm).My prolactin is 115, 3 (normal values 2, 8-29, 2ng/ml).I'm on thyroid medication. Probably have PCOS. Surgery or drugs?
Prolactinoma. You have a prolactinoma until proven otherwise. The best initial treatment is a medication that inhibits prolactin secretion from the tumor and acts to shrink it. The most popular one at this time is cabergoline that is taken twice per week. You may then watch the prolactin levels with periodic blood testing and watch the tumor with an MRI once per year or so. Rarely do you need surgery.
Likely need surgery. That is a sizeable adenoma. You likely need surgical treatment.
