pituitary tumor may be causing
Cushing's syndrome. It is sometimes done with an inferior
petrosal sinus sampling (IPSS) test.

to collect samples from blood vessels coming from the pituitary gland near the brain and also from a vein in your arm. First you will get a shot of CRH. Then samples of your blood near your pituitary gland and from your arm are taken.
If these blood samples
show high levels of
adrenocorticotropic hormone (ACTH) and cortisol, it usually

adrenal tumor or a cancerous tumor elsewhere in your
