Multiple sclerosis is an autoimmune disease that affects the brain and spinal cord (central nervous system). Multiple sclerosis (MS) affects women more than men. The disorder is most commonly diagnosed between ages 20 to 40, but it can be seen at any age. MS is caused by damage to the myelin sheath. This sheath is the protective covering that surrounds nerve cells.
Typically benign tumors, adenomas often press on the pituitary gland, causing loss of function of one or more hormones. Many pituitary adenomas are called âfunctioning tumorsâ because they actually make hormones and may cause an increase in hormone levels instead of a decrease.
Swerious thyroid problems can occur with ATCH-and TSH-producing tumors. Surgery to remove a pituitary microadenoma is a common course of treatment. Serious adrenal gland problems can occur with ATCH and TSH-producing tumors. A pituitary microadenoma is a very small, noncancerous tumor that forms in the pituitary gland.It is medically defined as a mass that is less than about 1 centimeter (10 millimeters) in diameter that grows slowly and does not carry any risk of metastasizing, or spreading, to other parts of the brain or body.s the pituitary gland is technically not part of the brain, pituitary tumors are not considered brain tumors. Some pituitary tumors are visible on MRI scans. Located in the head, the pea-sized pituitary gland produces hormones and regulates several other glands of the body's endocrine system.
