Adrenocorticotropic Hormone-Dependent Cushing’s Syndrome: Use of an octreotide trial to distinguish between pituitary or ectopic sources
Objectives: Adrenocorticotropic hormone (ACTH) overproduction is usually due to a pituitary tumour which is often not visible on magnetic resonance imaging (MRI). However, ACTH overproduction may be due to an ectopic source. This study aimed to develop a simple non-invasive technique to differentiate these sources. Met …
