macroadenoma or craniopharyngioma

Hello,

My brother has been suffering from unexplained extreme weight loss and fatigue for the last 10 years, and he has finally been diagnosed. Thanks to the endocrinologist, we discovered that he has adrenaline insufficiency, and this amazing Dr. requested an MRI to get to the bottom of his weight loss. We got the results which showed a tumor. We are seeing a neurologist in two weeks to learn more about the type of tumor, which could be either a macroadenoma or a craniopharyngioma.
I am worried about the type of tumor he has, but I am so glad this group exists for support.
