Got a q:
If a pt w/ abn 24h urinary cortisol, no response to high dexamethazone suppresion test and high ACTH. What is the Dx??
I know if 24hr unrary corisol is positive=cushing
no response to dexa supp test= r/o pit adenoma
you left with lung and adrenal but high ACTH goes with lung ca or any paraneoplastic synd, right? I found the answer is Adrenal ?? can someone please explain this for me? Plus, you do NOT have other lab w/ adrenal cause; high DEAS, high 17-KS.
Thanks
