Hey-
I had a Rathke's Cleft Cyst. So I know a fair amount of info about these. They are non-secreting.but tend to be located a little closer to the Hypothalamus than other types of Pituitary growths. Mine pressed on the pituitary stalk and caused me to have probs with both the anterior and posterior Pituitary hormones. They can expand and contract and affect your pituitary hormones to jump all over the place.
How are your Pituitary hormones?
Mine caused me to have low TSH, LH, FSH, ADH, ACTH, GH and elevated prolactin.
What kind of pituitary tumor?
There are plenty of people on line (such as a lot of people here, myself included). I had a prolactinoma and Cushing's disease. My cushing's tumor grew back so for me, this is a long term thing and I had my adrenals out as well.
