The dangerous literalistically brain
Asymmetry of the lateral ventricles of the brain, or literalistically, is not an independent disease. This is a symptom of individual pathologies of the brain resulting in increase in size of one or both ventricles.
Structure and function of the ventricles of the brain
In the brain has 4 ventricles. In them is produced and circulates CSF (cerebrospinal fluid). Its primary purpose is to transport nutrients to brain cells, removal of waste products, and cushioning the brain if the head bumps.
Two lateral ventricles(ventriculi lateralis) are located in the cerebral hemispheres, first left, second right. Normal depth of the sinuses — from 1 to 4 mm. increase in the capacity of body to 5 mm leads to a noticeable change of shape: lateral S-shaped curvature disappears, the cavity receives the rounded look.
In this case, talking about the initial stage of literalistically. Many wonder what it is and how dangerous this pathology?
Causes of asymmetry of the lateral ventricles
Expansion (dilatation) of cavities associated with the accumulation in them of liquor. The causes of this phenomenon are two: excessive production of fluid or the violation of the outflow.
The increase in the number of liquor provoke the following diseases:
- Hydrocephalus, which changes the absorption of the cerebral fluid.
- Central nervous system — schizophrenia, bipolar disorder.
Inadequate the circulation of cerebrospinal fluid occurs when the mechanical compression of the excretory ducts.
The cause of the phenomena usually become damaging factors:
- Traumatic brain injury;
- Vice Central aqueduct (the narrow canal that connects third and fourth ventricles);
- Bleeding in the brain;
- Intracranial tumors, cysts, papillomas, hematomas;
- Meningitis;
- Thrombosis of the veins of the brain.
Often literalistically of the brain occurs in infants, often preterm.
Whether it is dangerous?
No, in most cases, the extension of the anatomical cavity is a protective response to hypoxia of different nature (long attempts, suffocation by an umbilical cord). Over time, the body compensated for the anomaly.
Symptoms increase ventricular
The mechanism of development of pathology has common features, regardless of the reason. Fluid accumulates in the ventricles, they expand and compress brain tissue. Increased pressure within the cavities.
Patients complain of sudden headaches, nausea and vomiting, feeling of fullness in the eyeballs, impaired hearing and vision. The efficiency gradually decreases, arise memory disorders, lethargy, sleepiness.
All signs of pathology litwareproposal system. If the anomaly was not identified and treated in its early stages it becomes chronic.
Diagnosis
Asymmetry of the lateral ventricles is detected using the following procedures:
- Ultrasound of the brain — the most informative research;
- The fundus examination, detection of swelling of the disc of the optic nerve, spasms, hemorrhages;
- Neurosonography;
- MRI and CT of the brain.
If these methods give conflicting results, is assigned a lumbar puncture. Cerebrospinal fluid analysis reveals the cause of the deformation of the lateral sinuses.
Therapeutic measures
Diseases of the brain are the responsibility of the neurologist and neurosurgeon.
The asymmetry of the ventricles are usually prescribed drugs:

- Diuretic — Triampur, Diacarb;
- Nootropics — Nootropil, Encephabol, Piracetam;
- Sedatives — Somnol, Denormal;
- Antivirals or antibiotics, if detected any infection.
In the presence of tumor, hematoma or head injury is surgery. If, despite treatment, asymmetry progresses, the patient is assigned to ETV (endoscopic ventriculostomy).
The essence of the operation is that in the wall of the ventricle creates an additional hole through which the CSF flows. Technology is considered highly effective and safe, ensuring persistent improvement of the patient.
