Brain cyst in children

Brain cyst – such a diagnosis is found in the practice of a neurosurgeon quite often. In a large number of cases, cerebral cysts remain clinically “mute” throughout life,

Brain cyst in children

The liquid contents of the cavity may push the sticky sheets together, forming a blister or cyst. This is a typical mechanism for the formation of cysts of the lining of the brain. Most often, they are formed in a soft spider “mesh” covering the bark of the large hemispheres. Its tender layers are most vulnerable to injury or inflammation. This shell owes its name to the ancient doctors, to whom it resembled a web. So the name of the arachnoid shell (from the Greek. “Arachna” – spider). The same name was obtained and cysts, which are formed in the arachnoid membrane. These “balls” filled with fluid are always located on the surface of the brain.

If the cyst was formed in the brain, it is called cerebral or intracerebral. The cyst appears on the place of the deceased medulla, replacing the empty space formed after the loss of a portion of the nervous tissue. The cause of the death of a part of the brain tissue can be trauma, hemorrhage or inflammation. If the pressure in the cyst is higher than the total intracranial pressure, the cyst can squeeze the bark tissue and cause the corresponding unpleasant symptoms.

In children, cysts are formed as a result of inflammation that the baby has suffered in the womb (many women during the pregnancy suffer infectious diseases). Another cause of cysts can be trauma from childbirth. In children, the formation of cysts is prompted by the inflammation that the baby has suffered in the womb, or the trauma of childbirth.

Viruses that cause a mom runny nose, can easily cause meningitis in the fetus. The result of inflammation can be a cyst (most often – arachnoid,

Cerebral cyst

Cerebral (intracerebral) cysts in children are more likely to occur due to injuries. During childbirth, a large load falls on the head of the baby: it is the head that most often the child makes its way through the birth canal during attempts. Any obstacles on this road – narrow birth canal, exostoses, mom’s abnormal behavior, or careless obstetric care – lead to intracranial hemorrhages, which result in intracerebral cysts.

In adolescents, cerebral cysts in different locations (corpus callosum, subcortical nuclei, hemispheres, cerebellum, brainstem, etc.) are a collection of fluid at the site of a deceased part of the brain. The fluid thus replaces the lost volume of the brain substance. Common causes of cysts at a later age are cerebrovascular insufficiency, stroke, trauma, inflammation (encephalitis), surgery in the cranial cavity.


Depending on the type of tissue from which a cyst is formed, as well as its structure, a brain cyst can be:

  1. Arachnoid (enlarged sphere filled with cerebrospinal fluid).
  2. Colloidal (formed at the stage of the embryo, during the formation of the central nervous system).
  3. Dermoid (formed in the early weeks of fetal growth in the case of isolation of cells intended for the face, in the brain or spinal cord).
  4. Epidermoid (formed similarly dermoid, when skin cells, nails and hair enter the spinal cord or brain).
  5. Pineal (formed in the epiphysis of the brain).

Can brain cysts grow?

A brain cyst is not a cancer. The size of the cyst is easily monitored by MR imaging or CT. If the size of the cyst has become larger over time, it means that some damaging factor continues to act on the brain. In this case, it is important to find and treat the causes of the appearance of cysts.

The main reasons for the growth of arachnoid cyst:

  • In a cyst, fluid pressure increases;
  • Inflammation of the meninges continues (arachnoiditis, infection);
  • Concussion of a patient with a previously formed cyst.

The main reasons for the growth of intracerebral cyst (and / or the emergence of new cysts):

  • Continued violation of cerebral circulation, there are new foci of microstrokes;
  • The infectious or autoimmune process of destruction of the brain substance (multiple sclerosis, multiple encephalomyelitis, neuroinfection) continues.

The causes of the appearance or growth of cysts usually can be determined from the results of MRI scans, blood tests and blood flow through the brain vessels. Treatment is based on the results of research.

Symptoms of brain cyst in children

Symptoms are determined by the underlying disease that caused the appearance of cysts. Therefore, they are diverse and non-specific.

One or more of the following symptoms are possible:

  • Headache;
  • Feeling of pressure or pressure in the head;
  • Sensation of pulsation in the head;
  • Noise in the ear with sound hearing;
  • Hearing impairment (sensorineural hearing loss);
  • Visual disorders (double vision, spots before eyes and
