Cushing syndrome is commonly accompanied by the condition known as ACTH syndrome, which in most cases is due to an ACTH-producing pituitary adenoma.
It occurs when the adrenal cortex becomes overactive and cortisol production increases.
The most common cause of Cushing syndrome is hypersecretion of ACTH, where there is autonomous hypersecretion of the adrenal cortex due, in most cases, to an adenoma and, more rarely, to carcinoma.
