I don't think your cyst is causing a problem. An enlarged pituitary would be more likely a problem.
ICF-1 can be elevated for a few reasons:
Over induglence in protein.
However, GH should be measured several times.
If IGF-1 has not stabilized at a maximum level, then GH is not the reason for an increased IGf-1
I suggest you get a different endocrinologist even if you have to "go private" or that your gp take several GH measurements at different times.
