Brain cyst

Cyst – the pathological hollow education in bodies which is characterized by existence of the cover and liquid filling all cavity.

What is a brain cyst. Types of cysts of a brain

Brain cyst – the hollow education in structures of a brain filled with cerebrospinal liquid, which is characterized by various localization. Depending on type of the fabrics forming brain cysts, and localizations of educations allocate the following types of cysts:

• Arachnoidal cyst – the cystous education which arose between layers of arachnoidal (web) covers of a brain, filled with cerebrospinal fluid. It is more often shown at male patients (at children and patients of teenage age). If pressure in an arachnoidal cyst exceeds intracranial pressure, then in that case the cyst makes the squeezing impact on a cerebral cortex, causing characteristic symptomatology. The arachnoidal cyst of a brain can be inborn (forms as a result of disturbance of embryonic development) and acquired (forms as a result of the postponed inflammatory and infectious diseases);
• Colloid cyst of a brain – the cystous education arising at a stage of embryonic development in the course of formation of the central nervous system of a fruit. The colloid cyst can exist asymptomatically throughout all life of the patient. The main risk arising at a cyst of a brain of this kind is disturbance of current of liquor that leads to negative effects (hydrocephaly, formation of brain hernias, death);
• Dermoid/epidermoid cyst of a brain – the education appearing in the first days of formation of a fruit that explains detection in fabrics of a cyst of hair fibers, fat. Such type of cysts of a brain is characterized by rapid growth and is subject to surgical removal in order to avoid development of serious consequences;
• Pineal cyst of a brain – education in a pinus (epiphysis) of small volume. At untimely diagnosis of a pineal cyst of a brain disturbance of processes of a metabolism, sight, coordination, encephalitis, hydrocephaly can be effects.

Colloid, dermoid (epidermoid) and pineal types of cysts of a brain belong to cerebral (intracerebral) educations.

Brain cyst: education symptoms

At detection of a cyst of a brain symptoms can have as the general, and specific character. At a brain cyst symptoms are defined by the major factor which caused formation of a cavity. A number of symptoms, however, will depend on dynamics of growth and development of cystous education and its influence on structures of a brain.

Treat the main symptoms of a cyst of a brain:

• Feeling of a pulsation in the head, feeling of a raspiraniye or pressure in the head;
• Headache, frequent causeless dizziness;
• The broken coordination of movements;
• Hearing disorder;
• Sonitus at hearing preservation;
• Vision disorder (doubling of objects, blurring of images, spots);
• Hallucinations;
• Disturbance of sensitivity of skin, development of paralysis, paresis of extremities;
• Epileptic seizures;
• Tremor of hands, legs;
• Incidental loss of consciousness;
• Sleep disorder;
• Nausea, vomiting (meets at children more often).

It should be noted that most often development of a cyst of a brain has no bright symptomatology, the cyst is found at regular inspection of the patient.

Brain cyst: reasons of development of education

At detection of a cyst of a brain of the reason of its development – a main objective of diagnosis for definition of tactics of treatment. At diagnosis of a cyst of a brain, the following factors can be the reasons of its education:

• Disturbances of pre-natal development at which the cyst of a brain is congenital anomaly;
• Degenerative and dystrophic disturbances in a brain at which there is substitution of brain fabric cystous education;
• Brain injuries (including, patrimonial);
• Acute disorders of cerebral circulation.

Brain cyst at newborns: types of cysts, development reasons

The brain cyst at newborns is the hollow education filled with liquid, replacing the died site of a brain. Such educations can be single and multiple, have various localization.

Distinguish three main types of cysts of a brain at newborns:

• Cysts of vascular textures are norm option, arise at a certain stage of embryonic development, regress before total disappearance. Such cysts do not constitute danger to normal brain activity of the child. Much more dangerously the cysts of vascular textures which arose later the child's births are. Such educations are a consequence of the inflammations and infections transferred the woman during pregnancy. One of factors is the herpes virus;
• The Subependimalny cyst of a brain of newborns arises owing to a circulatory unefficiency of a brain and insufficiency of its oxygen supply. Is more serious violation. Dynamics of development of such education demands constant control;
• The arachnoidal cyst of a brain at newborns has the same etiology, as at adults. Education arises on brain covers, can increase considerably in a size, putting pressure upon surrounding structures of a brain, the progressing convulsive attacks, increase of neurologic symptomatology, deterioration in the general condition of the child can be a consequence of what.

Brain cyst: treatment, forecasts

When diagnosing a cyst of a brain treatment is chosen, proceeding from the education prime cause. Not dynamic cysts of a brain of treatment do not demand. At detection of a dynamic cyst of a brain treatment can be:

• Conservative – drug treatment which action is directed to elimination of the reason of formation of a cyst: the drugs, resorptional commissures recovering blood supply, antibacterial, antiviral, immunomodulatory drugs at infections and autoimmune diseases;
• Radical – operational removal of a cyst of a brain. The main methods – endoscopy, a craniotrypesis, shunting of a cyst (the risk of developing of an infection at long-term finding of the shunt in a head cavity is increased).

Brain cyst: disease effects

At untimely diagnosis and treatment of any type of a cyst of a brain of an effect can be various character:

• Lack of coordination, motive function;
• Hearing disorder and sight;
• Hydrocephaly (brain edema) – excessive accumulation of cerebrospinal liquid in ventricular system of a brain that is a consequence of its complicated movement from the place of secretion to the place of absorption;
• Encephalitis – the class of diseases which is characterized by inflammatory processes of a brain of various localization and an etiology;
• Sudden death of the patient.
