Tumors of the pituitary: symptoms, diagnosis, treatment

Pituitary Tumors - Causes, Diagnosis And Treatment (Health And Medical Video June 2018).

Pituitary gland tumors - benign or malignant tumors. Most often there is an abnormal growth of the cells of the gland, sometimes in the pituitary gland, other germs of the brain may sprout, possibly also metastases from malignant lesions localized in other parts of the body.

Causes of pituitary tumor

Most often, the tumor is affected by the anterior part of the pituitary gland (adenogupophysis), and rarely - the posterior particle (neurogipophysis).

The reasons may be:

  • Negative effect on the fetus during pregnancy;
  • Taking hormonal drugs;
  • Infections;
  • Injuries;
  • Hereditary predisposition.

Symptoms of the pituitary tumor

Symptoms associated with the effect of a growing tumor on adjacent brain tissue:

  • Headaches
  • Vision impairment, nystagmus, duality in the eyes, limitation of eye movement, ptosis (omission of the century);
  • Increased intracranial pressure;
  • Change of personality;
  • Convulsions;
  • Chronic undead

80% of the tumors of the gland are hormonal-active and have symptoms associated with excessive or deficient hormones of the pituitary gland.

As a result, these pathological conditions may occur.

  1. Central hypothyroidism - a decrease in the production of thyrotropic hormones and disorders of the thyroid gland, characterized by an increase in body weight, constipation, reduced pressure, hair loss, weakness;
  2. Cushing's syndrome is an increase in adrenocorticotropic hormone production in the pituitary gland and, as a consequence, cortisol in the adrenal glands. Symptoms: deposition of fat on the neck, face ("moon-shaped face"), abdominal distension, high blood pressure, muscle atrophy, tiredness of the skin;
  3. Acromegaly, or gigantism, is an increase in the production of a growth hormone, which causes an increase in palms and feet, headaches, fatigue.
  4. Prolactinoma in women may cause meager menstrual discharge or absence of lunar, milk in the chest outside the state of pregnancy and breastfeeding, in men - breast enlargement, erectile dysfunction, infertility, decrease in libido.
  5. Less can be the clinical picture of thyrotoxicosis - a decrease in body weight, an accelerated heartbeat.
  6. If the tumor is damaged, the hormone-producing cells can completely suffer their function and develop hypopyutriism - the deficiency of all the pituitary hormones.

Diagnosis of the pituitary tumor

Diagnosis includes blood and urine tests on hormones, magnetic resonance imaging of the brain, ophthalmologic examination (estimation of visual fields).

Angiography of the vessels of the brain may be performed to clarify the diagnosis and exclude intracranial aneurysms.

Treatment of pituitary tumor

The most effective method is the surgical removal of the tumor. Neoplasms are removed either frontal with an optical device, or through a wedge-shaped bone. After surgery, hormone replacement therapy is indicated.

In the presence of contraindications for surgical treatment or in the presence of a small hormonal-inactive tumor, radiotherapy is used.

Prolactin and ACTH-secreting education can be treated with pharmacological dopamine agonists.

With early detection, small size and the possibility of complete surgical resection, further prognosis in tumors of the pituitary gland is favorable.
