Guide To The Types of Pituitary Tumors

Adrenocorticotropic Hormone Tumors

An adrenocorticotropic hormone tumor, also called an ACTH-producing tumor, refers to an abnormal growth in the pituitary gland that causes the production of too much adrenocorticotropic hormone. These tumors originate in corticotropic cells, which are responsible for producing ACTH. This hormone commands the adrenal glands to produce cortisol, which is also known as the stress hormone. Cortisol helps the body cope with all types of stress. This cortisol release and its subsequent effects work great for when the body is under stress from an injury, infection, or recent surgery. However, numerous adverse effects arise when too much cortisol is in the body due to its production by an ACTH tumor, including unexplained weight gain, muscle weakness, high blood pressure, moodiness, insomnia, irregular periods, bone weakening, fractures, limb thinning, diabetes, easy bruising, and poor concentration. ACTH tumors are diagnosed through MRI scans of the patient's brain, urine tests, blood tests, and petrosal venous sampling.
