Neurinoma( Schwannoma) of the brain is a tumor originating from cells of the nerve endings( Schwann cells).Neurinoma is considered a benign tumor, but in practice, there are malignant formations of this pathology. Neurinoma can form almost anywhere in the body( mainly the brain, auditory or trigeminal nerve).The causes of the appearance of neurinoma in the body have not yet been studied. Scientists suggest that this is due to a malfunction of the immune system and a hereditary predisposition.

Causes of neurinoma

The main causes of this disease, modern medicine could not be identified. With a high degree of probability, scientists only call the only reason for the appearance of the disease - this is a hereditary predisposition. Scientists, on the basis of studies, it was proved that neurinoma of the brain is inherited. If the parent had this disease gene, then the probability that a child will be born with the same disease is 50%.

If the pedigree did not have the incidence of this disease, then the second reason is the decrease in the immune system. On immunity in our time, everything acts: a polluted environment, stress, constant rush and a sedentary lifestyle. All these factors negatively affect our health and adversely affect immunity. And in the end it leads to the appearance and development of a tumor. Protect your brain from the existing misfortune is beyond anyone's power, but avoiding stressful situations and maintaining a healthy lifestyle will strengthen the body.

Symptoms of neurinoma

Symptoms of neurinoma of the brain are the following:

1. When the tumor is squeezed part of the nerve, there is a violation of the coordination of the vestibular apparatus. A person loses balance( such symptomatology is observed in 60% of cases of the disease), the gait becomes unstable. He suffers from constant dizziness
2. When the tumor is squeezed by the tumor of the facial nerve part - there is numbness of the face, the person experiences a tingling of the skin, from the nerve clench, taste changes
3. When the tumor squeezes the cochlear nerve part - this happens in most cases. This leads to hearing loss( 90% of cases)
4. When the tumor is squeezed by the tumor of the auditory nerve, a one-sided, increasing hearing loss occurs. Also, a person experiences constant noise in the ears, from the side where the

tumor was formed. With increasing tumor size, the symptomatology changes, the patients often complain of dizziness, disruption of movement coordination, and numbness of the facial muscles. With the progression of the disease, when the size of the tumor becomes the size of a walnut, the most radical symptoms are revealed: complete deafness, decreased sensitivity of the cornea( in 90% of cases), rapid eye movements impairment of taste. When reaching a large tumor( for example, with a chicken egg) - the main symptom is a violation of vision and mental state, as well as problems with swallowing.

Types of brain neurin

An increase in benign neurinoma of the brain occurs slowly. A kind of capsule forms around it, which limits it from closely located cells and tissues. But malignant neurinoma grows very quickly. Such a tumor has the property of invasion( that is, the introduction into healthy organs and tissues).Already at an early stage gives metastases, which primarily damage the lymphatic and nervous system.

Diagnosis of neurinoma of the brain

To establish an accurate diagnosis, CT and MRI are performed. A biopsy is also done, which helps to identify the cellular structure and structure of the tumor. The main tomographic symptom of the disease is oval( or round) volumetric formation, which is located in the temporal bone or in the area of ​​the cerebellar angle.

Treatment of neurinoma of the brain

1. Conservative treatment Conservative treatment of brain neurinoma carried out by assigning the following drugs:
   - Mannitol( mannitol as a 20% solution intravenously, by drip for 10-15 minutes for the extra reducing intracranial pressure is carried out in combination with glucocorticoids required.monitor urine output and fluid and electrolyte balance. If necessary, a second infusion of mannitol in lower doses. mannitol used shortened course until effKTA glucocorticoids or curative treatment, since it may contribute to the secondary increase in intracranial pressure
   - Glucocorticoids:.. dexamethasone( oral or parenteral) 4 Hour or prednisolone After the radical treatment( radiotherapy or surgical decompression) hormone dosage is gradually decreased
   -.drugs for cerebral circulation improvement( Cavintonum, nicergoline). The use of strong sedatives and neuroleptics undesirable since they odBna mask the deterioration of the patient.
2. Surgical treatment. Surgical treatment is prescribed in case of a serious condition of the patient, an increase in the size of the tumor and an increasing metastasis. The interference is carried out to remove the tumor biopsy and determination method of treatment or as palliative measures( decompressive trepanation).
   The operation is performed for the purpose of radical tumor removal. When the tumor is located in the depth or on the surface of the hemispheres, the most common is bone marrow transplantation. If it is located in the posterior cranial fossa, resection is performed. When the tumor is completely removed it is not possible, then its extensive resection is desirable.
   
3. Complex treatment - radiation and chemotherapy. It is mainly used with an immature( malignant) tumor and when it is impossible to radically remove the neurinoma.

In more advanced cases occurs complication - gryzhevidnoe displacement or bulging of the brain via intracranial rigid formation( skull, the foramen magnum) in reducing brain protecting properties and continuing increase in tumor size.
