General Information
Pituitary tumors represent from 10% to 25% of all intracranial neoplasms.
Pituitary tumors. Most cases of acromegaly are caused by a noncancerous (benign) tumor (adenoma) of the pituitary gland. The tumor secretes excessive amounts of growth hormone causing many of the signs and symptoms of acromegaly.
Pituitary Tumors - The pituitary gland is located in the brain and assists with regulating the activity of the adrenal glands as well as most of the other glands in the body.
Pituitary tumors are described in several ways.
Pituitary tumors are described by their size and grade, whether or not they make extra hormones, and whether the tumor has spread to other parts of the body.
The following sizes are used: ...

The pituitary gland is a gland located at the base of the brain. It produces hormones that control many other glands in the body.
pituitary tumor: Abnormal mass in the pituitary gland.
renal: Pertaining to the kidneys.
secretion: Process of producing a substance from the cells and fluids within a gland or organ and discharging it.

[ 7 ] Endocrine-inactive pituitary adenomas comprise approximately 30% to 35% of the pituitary tumors in most series and are the most common type of macroadenoma.
Pituitary tumors were, historically, classed as basophilic, acidophilic, or chromophobic on the basis of whether or not they took up the stains hematoxylin and eosin.

ACTH (cosyntropin) stimulation test measures how well the adrenal glands respond to the hormone ACTH. ACTH is a hormone produced in the pituitary gland that stimulates the adrenal glands to release cortisol.
Pituitary Tumors. Pituitary tumors comprise about 10% of primary brain tumors and are often benign, slow-growing masses in the pituitary gland.

A tumor that forms in the pituitary gland. The pituitary is a pea-sized organ in the center of the brain above the back of the nose.
A pituitary tumor causes symptoms by any of three mechanisms:
By producing too much of one or more hormones.
In pituitary tumors with well-defined borders, surgery is the treatment of choice and can cure many cases.
Most pituitary tumors arise spontaneously and are not genetically inherited. Many pituitary tumors arise from a genetic alteration in a single pituitary cell which leads to increased cell division and tumor formation.

Prolactinoma is an adenoma (benign tumor) of the pituitary gland. Causes of many prolactinomas are unknown.

Women can more easily identify a potential pituitary tumors than men because such growths usually disrupt menstruation. Men, on the other hand, are rarely given dependable indicators of a prolactinoma until the onset of far more serious complications.

Radiation - Radiation can be a useful treatment when pituitary tumors cannot be completely removed by surgery. Radiation of pituitary tumors reduces cortisol levels in about half of adults and most children with Cushing's disease.

A prolactinoma is a noncancerous pituitary tumor that produces a hormone called prolactin. This results in too much prolactin in the blood.
Causes, incidence, and risk factors:
Prolactin is a hormone that triggers lactation or milk production.
If the amenorrhea is caused by a tumor in the brain (pituitary tumor), the tumor is usually treated with a drug called bromocriptine. Surgery to remove the tumor may also be necessary.
This can affect many functions, including hormone-making and vision. These tumors occur in adults and children.

Hypopituitarism, in children, is often caused by a benign (non-cancerous) pituitary tumor, an injury, or an infection. However, often no exact cause can be determined.
What are the symptoms of hypopituitarism?
Increased and unregulated growth hormone (GH) production, usually caused by a GH-secreting pituitary tumor (somatotroph tumor), characterizes acromegaly.
