My 18 year old daughter has symptoms of Cushing's disease, but her bloodwork, urinalysis, and ct scan of her adrenal glands came back normal. They did not scan her pituitary gland. She has gained about 70 lbs. in the past two years, she has stria (purplish stretch marks), extreme fatigue, inability to tolerate heat, moodiness, etc. Is there another disease that mimics Cushing's?
