A pituitary adenoma is a tumor-that is, a growth of tissue in which cells multiply in an uncontrolled manner. Adenomas are located just next to, or within the pituitary gland. The adenoma can be much smaller than the gland when the symptoms it causes become noticeable and the adenoma is diagnosed. Most pituitary adenomas are 'microadenomas', which measure 3 to 9 mm (1/8 to 3/8 of an inch) in diameter, although a few patients have 'macroadenomas', which are 10 mm or larger in diameter.

No, It can produce endocrine problems by which it may be suspected and then subsequently detected by CT scan.

No. The Pituitary adenoma has to grow considerably (approximately 10 mm above) to press on the chiasma to produce field defects.

A pituitary tumor is a tumor that begins in the pituitary gland. Most pituitary tumors are not cancer. In fact, cancerous pituitary tumors are so rare that state and national cancer agencies keep no record of how many people get them each year. Benign (non-cancerous) pituitary tumors are also rare. About 3,000 people get them each year.

The pituitary gland is a small gland located behind the nasal sinuses and above the roof of the mouth at the base of the skull. It is connected to the hypothalamus, a part of the brain. Together, the two control the production of many of the important hormones in the body. The pituitary gland sits in a tight bony space and has little room to grow or expand when swollen or if there is a tumor.

CDI itself does not interfere with menstruation or fertility. However, it may be associated with these or other problems if the disease or injury that caused the DI also damages adjacent parts of the brain or pituitary where other hormones are normally produced. Head trauma is one of the things that can cause this kind of collateral damage, but it does not always do so. Therefore, each patient with CDI must be evaluated separately to determine if any of the other hormones have been affected.

Pituitary tumors that affect hormones may cause a variety of symptoms, which are related to high hormone levels and production. These symptoms will be different in children than in adults. Growth hormone-secreting adenomas in children may cause: Other more rare kinds of pituitary tumors cause other symptoms. It is important for anyone who is experiencing any unusual symptoms to see their doctor.

In most cases, pituitary tumors are treated by surgery, radiation therapy, or by using drugs that block the tumor's ability to produce hormones. Surgery: The goal of surgery is to remove the entire tumor from the pituitary gland. This is possible with most microadenomas but may be less likely with macroadenomas. Sometimes the entire pituitary gland will have to be removed. Medications can provide the hormones that the pituitary gland used to produce.

This depends on the type of tumor and the size of the tumor. A large tumor may cause loss of vision, particularly peripheral vision, if it compresses the optic chiasm (where the optic [eye] nerves converge). Headache may also occur; the type of headache varies from patient to patient. Headache may occur with a large or a small tumor.

ACTH deficiency: ACTH stimulates the adrenal glands to produce cortisol. Cortisol is essential for life. When cortisol is inadequate, patients experience fatigue, weakness, weight loss, nausea and vomiting, low blood pressure and may develop shock and die unless treated. TSH deficiency: TSH stimulates the thyroid gland to produce thyroid hormone. Low thyroid hormone causes fatigue (loss of energy), weight gain, constipation, dry skin, and feeling cold.

Certain factors can make one person more likely to get a pituitary tumor than another person. These are called risk factors. In some cancers, doctors have identified risk factors that can be avoided, such as smoking or sun exposure. With pituitary tumors, doctors are not sure what exactly causes pituitary tumors and only one risk factor has been identified. Most people who get a pituitary tumor have no known risk factors.

Microadenomas do not cause CDI. However, infiltrative diseases of the pituitary, which can mimic micros on MRI, can. Given your symptoms, you should have tests to determine whether you do, indeed, have CDI.

Hi. I'm a nursing student and I recently had a male patient, 64 yrs. old, who is diagnosed with Diabetes Mellitus type 1, obesity, hypertension, a right below-the-knee amputation due to osteomyelitis, depression, chronic renal insufficiency, and a few other things, including poor wound healing. He has the typical Cushing's body type and the buffalo hump. He has no striae on his abdomen.

The pituitary, or master gland, controls the function of many other glands - the thyroid, adrenals, ovaries, testes. It also produces growth hormone and anti-diuretic (water saving) hormone.

The anterior pituitary peptides are bio-engineered parts of molecules from glandular extracts. Glandular products have been used in Europe for years and are usually taken from animal sources such as lamb, bovine or porcine. These are pharmaceutical grade and especially prepared from disease free herds and flocks.
