The brain cyst: types, symptoms, treatment.
A brain cyst is
The brain cyst: causes.
Cyst are caused by different reasons, but the mechanism of its formation is similar in all cases. The cerebrospinal fluid circulates in the tissues of the back and head, protecting nerve cells from any mechanical stress, damage, inflammation. In other words, whenever a problem arose with nerve cells or the brain substance, forms a tributary of the liquid to the affected area. Cerebro-spinal fluid contributes to its healing and protection. But too extensive, the damaged area of tissue in the skull or poor blood circulation cause accumulation. So the body tries to compensate for the lost tissue by replacing it with a liquid. Which leads to the cyst.
The main causes of cysts are:
- Congenital pathology.
- The consequences of birth asphyxia.
- Brain contusion, skull fracture.
- Parasitic lesions of the brain.
Symptoms of cyst in the brain.
The size of the cysts of the brain vary within a fairly wide range. A small cyst in most cases does not cause any symptoms and is detected only in the study of the brain by ultrasound, MRI, etc. and the formation of large size creates a pressure on the tissues of the brain and its membranes, causing a number of symptoms from the patient. Their list is quite extensive, as the symptoms depend on what part of the brain the cyst presses:
- Hearing loss and vision deterioration;
- Headaches that do not pass after taking the pills;
- Deterioration of movement coordination and orientation in space;
- Paralysis or numbness of the hands and feet;
- Emotional instability, neurosis, nervous breakdowns, fits of anger;
- When a large cyst may cause serious mental illness – memory loss, the development of dementia;
- Cramps in the muscles;
The types of cysts of the brain.
Depending on the type of tissue, which was localized tumor, all the cysts are divided into two types: arachnoid – located in the meninges, and retrocerebellar – occur directly in the brain tissue.
Depending on the location there are several types of cysts:
- a cyst of the choroid plexus.
- a cyst of the septum of the brain.
- lacunar cyst in the brain
- parencephalons the cyst.
- a cyst of the cerebellum of the brain.
- a cyst of the pituitary gland.
Arachnoid cystsof the brain.
This type of cyst is formed in solid, arachnoid and soft meninges. Localized in any place of the shell, and includes several subtypes cysts. There are primary arachnoid cysts – congenital, and secondary – formed after illness. Its occurrence is facilitated by:
- postoperative period if the operation is carried out on the brain);
- Marfan's disease (abnormality of the connective tissues), etc.;
A cyst of a transparent septum of the brain.
This type of arachnoid cyst localized between the anterior lobe and corpus callosum of the brain. This type of cyst can be congenital or acquired. Congenital cyst of the septum often does not harm the brain, but acquired the required supervision of a specialist, as it can grow.
Lacunar cysts are formed in the gaps (voids) between the membranes of the brain.
Retrocerebellar cysts of the brain.
Formed this type of cysts in all parts of the brain, which develops necrosis. Replaced dead brain matter CSF fluid. Their causes can be many. The main difference retrocerebellar cysts from arachnoid that it is growing, and quickly. It is, and this is a danger for health and sometimes for life.
This cyst is localized in the third ventricle of the brain and is a cavity of neuroepithelial SCS or cells filled with a thick jelly-like liquid. Such a cyst is congenital, the result of mutation, which is inherited. Usually is small in size and does not threaten human health.
The pineal brain cyst (cyst of the pineal gland).
The pineal gland has many important functions: produces melatonin, defining the human biorhythms, affects the immune system, in a timely manner eliminates the growth hormones in his youth, regulates sexual development. A cyst in the body of the gland is rare. And the reasons are the violation of the circulation of melatonin or the parasite Echinococcus.
Epidermoid (dermoid) cyst of the brain.
There is a theory that this type of cyst is congenital, and is formed during formation of the fetus from the cells of the epidermis, which accidentally fell into the cranial space and remained there. It is located in the middle of the brain closer to its barrel. The sizes can be different. This type of cyst is veryeasy and estrumate removed due to the structure of her body well separated from the medulla and connective tissue.
Cyst of the choroid plexus of the brain.
This cyst is typical for newborn babies. It is formed in a regular manner at a certain stage of formation of the fruit: the choroid plexus produce Livorno (brain) fluid, which nourishes the brain and spinal cord. In the last months of pregnancy when normal for these cysts disappear on their own.
If the baby was born with a vascular brain cyst, this may be a consequence of the transferred mother during pregnancy, infectious diseases, a sharp decrease in its immunity or the result of improper management of pregnancy. Typically, these cysts in toddlers dissolve until a year or two. Nevertheless, up to this point requires regular examination of the child. In adults, this cyst is also common and usually does not cause discomfort.
Tumors of this type are localized in any part of the brain substance on the spot of dead tissue. Dangerous types of cysts, can lead to the development of diseases such as
Diagnosis and treatment of cysts of the brain.
Cyst of the brain diagnosed by an MRI with contrast. To identify the causes of its formation should be:
- Doppler scanning of cerebral vessels.
- To examine the heart.
- To explore the level of cholesterol in the blood.
- The study .
- To verify the presence of infection in the blood.
- To exclude the presence of parasites.
- To investigate the dynamics of cyst (speed of growth).
Only after a comprehensive examination specialist assigns appropriate treatment of cysts and diseases, which provoked its emergence.
Treatment of cysts is prescribed depending on its type. Static cysts of small size do not need any treatment and does not affect the operation of the brain, however, requires constant medical supervision.
Cysts of medium size, it is often possible to overcome through drug treatment. For this cure the disease that contributed to the formation of cysts. And her body is independently resolved after eliminating the cause.
For example, if the cause of the cyst was the narrowing of blood vessels, vasodilators preparations, antispasmodics and drugs that reduce cholesterol in the blood. If the reason was href="http://headache.vsebolezni.com/sosudy/davlenie/gipertoniya-simptomy-diagnostika-i-lechenie.html">hypertension – treated her, and so on.
Large cysts require urgent surgical intervention, make it difficult because the brain, damage to his tissues, disrupt the thought process and entire body.
Surgery to remove a cyst of the brain are divided into three types.
Mean examinations of the skull and complete removal of the cyst along with its shell. Provides a comprehensive remedy the problem without the possibility of relapse. The method is very effective, but is the most traumatic to have ever existed.
How does the removal of an arachnoid cyst of the brain:
In the bones of the skull made a neat puncture, which is inserted through the drainage tube into the body of the cyst. With its help pump out the contents of the cyst. The body of the cyst is "blown", the walls are gradually dissolved. The method has a low injury rate. The lack of it in higher probability of infection in the puncture.
- The endoscopic method.
The safe and atraumatic way to remove cysts. Produced by introduction into a puncture in the skull of an endoscope with a video camera. The contents of the cyst is removed, its walls subside and resolve. However, the disadvantage of this method is that it is not suitable for all types of cyst of the brain.
Because the formation of cysts in the brain susceptible to many age categories, periodic examination of the brain (e.g., MRI), recommended to everyone at least once in every 1-3 years.
