Among the most commonly diagnosed diseases of the brain –
pituitary adenoma of the brain. What it is? it
benign neoplasm that occurs in 15%
cases of all brain tumors.

Гипофиз — главная железа в организме,
regulating the activities of almost all systems. Therefore dangerous
is any deviation in his work.

What is pituitary adenoma?

The pituitary gland is an endocrine gland,
located in the lower part of the brain near the Turkish saddle.
The pituitary gland is responsible for the production of growth hormones, sex hormones,
hormones involved in metabolism.

Аденома гипофиза головного мозга — это доброкачественная
, расположенная в передней доле железы. Exactly at
hormones such as TSH, ACTH,
LH, FSH, prolactin. Pituitary adenoma occurs in people of age
from 30 to 50 years. Children are diagnosed very rarely. In most
cases, the disease is asymptomatic, the first signs
appear when the tumor is already large and requires
deletion. According to ICD 10, the disease has the cipher code D35.2.

The causes of pituitary adenoma in the brain are still
pores not exactly installed. There is a version of its secondary origin.
First, changes occur in the hypothalamus, which begins
increased pituitary stimulation. The result is hyperplasia.
glandular pituitary cells (enhanced proliferation).

The provoking factors of the appearance of adenoma include:

  • Травмы головы (особенно затылочной
  • Инфекции (энцефалит, менингит).
  • Туберкулез головного мозга.
  • Осложненная беременность и роды.
  • Прием оральных контрацептивов.
  • Курение и алкоголь.

Depending on the size of the adenoma are divided into microadenoma (less than
1 cm) and macroadenoma (more than 1 cm). Tumor can be hormonal
active (60%) and hormonally inactive. Impact of a different kind
The tumor on the body is different and has a different manifestation.

Hormonally active tumors are classified by type of hormones,
which they produce:

  • Somatropinoma.
  • Prolactinoma
  • Corticotropinomy.
  • Thyrotropinomy.
  • Gonadotropinoma.

Symptoms of pituitary adenoma

Usually microadenoma does not manifest itself, especially if it
hormonally inactive. The expressed symptoms gives adenoma large
sizes producing hormones. Symptoms of adenoma in men
somewhat different from the symptoms in women, as the tumor
produces different hormones.

The signs of adenoma are divided into neurological, that is,
growth-related tumors, and endocrine, associated with excess
hormone production. Neurological symptoms are not
specific, so they often start treating other diseases, and
the tumor in the meantime increases in size.

симптомы аденомы гипофиза

Main neurological symptoms:

  • Decreased visual acuity. The pituitary gland is located near the visual
    nerves, the tumor provokes a squeeze. The person can start
    to develop a squint, a feeling of ghosting in the eyes, the impossibility
    focus on the subject, the disappearance of lateral vision. Sometimes
    there are difficulties with turning the eyes.
  • Constant nasal congestion. May also develop
    persistent runny nose.
  • Dull headache, not passing after taking
  • Unreasonable fainting.

A macroadenoma that does not produce hormones, puts pressure on
pituitary, therefore, reduced synthesis of hormones. it провоцирует
development of the following pathologies:

  • Disruption of thyroid activity. Manifested by weakness
    fatigue, dry skin, swelling.
  • Violation of the adrenal glands. Patient is experiencing
    fatigue, dizziness, poor appetite, low
  • Violation of sexual function. In men, impotence develops,
    women – menstrual disorders, infertility.

Homonally active adenomas give symptoms depending
excessively produced hormone:

  • Somatotropinom. This tumor is more common in adolescents,
    causing gigantism, disproportionate growth of the skeleton. In adults
    obesity, strong body hair growth, sugar
  • Corticotropinomy. Produces ACTH in large quantities. Have
    The following signs are observed in patients: obesity (mainly
    on the abdomen and chest), increased blood pressure, decreased immunity, weakness
  • Prolactinoma Affects sexual function and causes
    infertility, impotence, aminorrhea, acne in adults. itт вид
    tumors are more common.
  • Thyrotropinomy. Causes the thyroid gland to produce hormones. AT
    As a result, the patient appears: arrhythmia, jumps in blood pressure, violation
    digestion, chills, weight loss, mood swings.
  • Gonadotropinoma provokes a lack of sex hormones. it
    manifested by decreased libido, cycle failure in women.

Due to non-specific signs of pituitary adenoma of the brain
difficult to diagnose. Not always the doctor can suspect
clinical tumor.

The main diagnostic methods are:

  • Анализ крови на гормоны. Elevated or
    low levels of any hormone can be suspected
    the presence of tumors.
  • MRI it самый информативный современный метод
    research. It allows you to accurately determine the localization of the tumor in
    head, its structure. Difficulties in diagnosis cause only
    microadenomas that grow very slowly. Even a powerful machine
    MRI is not always able to detect such an education.

The danger of pituitary adenoma of the brain

Than опасна аденома, если ее не лечить? Progressive development

hypertension, persistent headache and dizziness. Hormonally
active tumors disrupt endocrine and genital
functions, the disappearance of menstruation in women, impotence in men and
the development of infertility in both sexes. Have детей аденома

Also, some types of adenomas can be reborn in
malignant tumors, give metastasis. AT этом случае у больного
