One of the key issues with pituitary tumors is that there's currently no way to know if a benign pituitary adenoma will become cancer and grow and spread to other parts of the body.

Your doctor may recommend observation — or a ''wait and see'' approach. Watch this video about: Pituitary gland As a pituitary tumor grows, the normal hormone-releasing cells of the pituitary may be damaged.

The posterior lobe typically forms a sheet of tissue at the base of the pituitary stalk, and in most cases sends irregular finger-like projection into the tissue of the anterior pituitary, which lies directly beneath it. This type of tumor most commonly causes sexual dysfunction in men and loss of regular menses and infertility in premenopausal women. Past medications can also be relevant since long term steroid use is often related to hormone imbalance. The signs and symptoms of pituitary tumors that don't make hormones nonfunctioning are related to their growth and the pressure they put on other structures.

The following tests and procedures may be used: Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. High- dose dexamethasone suppression test: A test in which one or more high doses of dexamethasone are given.
Treatment of Destruction of the Pituitary Gland in Dogs Puppies with pituitary dwarfism are given various hormone treatments. In women their main effects are on the ovaries, where they control ovulation the release of eggs and the production of the hormones estrogen and progesterone.
The kind of hormone an adenoma makes strongly affects what signs and symptoms it causes. They sometimes press on the pituitary and the hypothalamus, causing hormone problems.
So, if the tumor gets larger than about a centimeter about half an inch across, it may grow upward, where it can press on and damage nearby parts of the brain and the nerves that arise from it. Symptoms include a severe headache and vision Tumors of the pituitary gland book, such as double vision or vision loss.
The provider will note any problems with double vision Tumors of the pituitary gland book visual field, such as a loss of side peripheral vision or the ability to see in certain areas. Dogs in an Addisonian crisis may need emergency treatment with intravenous fluids and electrolytes.
MRI magnetic resonance imaging with gadolinium : A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the brain and spinal cord. The veterinarian may order tests to evaluate the functionality of other endocrine glands and determine the source of the problem.
Teratomas, germinomas, and choriocarcinomas are all rare tumors that usually occur in children or young adults. The level of cortisol is checked from a sample of blood or from urine that is collected for three days.
