i read an article that was about the many different causes of empty sella one of them being thyroid cancer. it lead me to a link i will post here about an ectopic ACTH source in a vaginal lining malignancy. I have found in my own studies that it is beneficial to be vigilent about rooting out the source of our cushings. some doctors just want to offer multiple band aids. like in my case. doctors suggested removing my pituitary gland or my agrenal glands or trying to sustain me w/tons of insulin & hight blood pressure meds or ketoconazol. they did not get that i had 2 little ones to take care of. i wanted to stop my body from rotting. i knew i had little time left. i did not want agonizing prolongment. i wanted the SOURCE of the cushings hunted down & cut OUT of my body. in my hereditary type of cushings even removing a small portion (debulking) of the tumor, mass, cyst, watever your radiologist wants to call it, can save or add years to your life. it is hard to find such an agressive doctor. in my case it was my sisters who stood up to doctors. demanding they order a full body octreotide scan where they found the source of my cushings, a lung tumor that did not show up on other scans. the tumor can be ANYWHERE in your body. It will produce many different hormones not just ACTH. it can be the size of a spec of dust. Looking for these other tumor markers or hormones in 24hr urine catches besides just cortisol can put us closer to our cure. since i am posting a research link i picked this forum. if it is misplaced i apologize. please see this research link: http://lib.bioinfo.pl/pmid:9190988 our illness is not rare but doctors are not taught how to diagnose it. sometimes they need our help. we need to educate ourselves. my education on this website led to my cure. thank u MaryO for giving us this medium.
