The human brain has a complex structure. The bridge-cerebellar angle is located at the junction of three sections: the warolium bridge, the medulla oblongata, and the cerebellum. Often it is here that tumor growths appear, which have a negative effect on the blood vessels, the movement of the cerebrospinal fluid and nerve endings. This is due to the compression of these elements. As a result, blood flow does not supply the brain with oxygen sufficiently. Cerebrospinal fluid is not able to leave, accumulates, exacerbating the situation.
Cerebellar angle disease
Damage to a part of the brain occurs under the influence of neoplasms. A tumor of the cerebellar cerebellar angle is not one of them that occupies a certain position. In this case, damage occurs in any structure located at the site of the manifestation of the pathology. The disease is classified into types that undergo various therapeutic measures.
Types of tumors of the cerebellar cerebellar angle
Medical statistics point out an important fact. It consists in the fact that ten percent of a hundred formations in the brain are located in a place called the cerebellar angle.
Types of tumors associated with lesion site:
- neuroma of the vestibulo-cochlear nerve;
- meningioma;
- cholesteatoma.
The first disease accounts for 95 percent of all formations of the cerebellopontine angle. The detected tumor is benign and does not become a source of damage to other organs. At risk are patients of working age. Often, neuroma is found in women. Today, doctors prefer to remove the tumor operatively, while performing one-sided removal or bilateral.
Doctors often make a diagnosis of cerebellar cerebellar syndrome. It should be noted that it is a consequence of another disease called neurinoma.
Symptoms
It is not always possible to detect a tumor in the brain in time, because there are no good reasons for a full examination. The clinical picture is weak, there are no sharp jumps associated with a deterioration in well-being. The patient for a long time does not pay attention to the noise in the ear. This phenomenon is called cochleovestibular syndrome.
Gradually, the symptoms of the disease become more intense. As a rule, it is manifested by the appearance of deafness, the facial nerve is immobilized. Only after this a full examination is carried out, and the patient immediately goes to the operating table to remove the tumor.
It is noted that this stage becomes the first bell about a developing disease that requires attention.
The clinical picture of the signs of the disease
The manifestations of the pathology are as follows:
- Headache.
- The reflex responsible for closing the upper and lower eyelids is disturbed if you try to touch the cornea or conjunctiva with a napkin. This means that the patient requires a complete and in-depth examination.
- Phenomena present in the cerebellum. They also have several varieties, including general cerebellar ataxia, unilateral hemataxia. The patient has gait disturbances, the tone of the muscular system decreases. There are complaints of dizziness.
- Hands and feet refuse, paralysis occurs.
When a patient is diagnosed with a lesion of the cerebellar cerebellar angle, then the following signs of the disease are added to the indicated symptomatology:
- With neurinoma, disturbances will be felt in only one ear.
- The defeat in the auditory site in the first periods of the disease is manifested by noise or whistling in the inner ear.
- Gradually, the state of the organ becomes worse, deafness occurs. The only sound the patient can still hear is only high tones.
The position of the neurinoma in the brain indicates a future source of negative influence. This means that when the right side of the cerebellar cerebellar angle is damaged, organs located, respectively, similarly for the left hemisphere will suffer.
Additional symptoms
Also, the disease can manifest itself as follows:
- In the occipital part of the head, patients experience a pain syndrome localized where the tumor is located.
- The facial nerve is not sensitive to external stimuli.
- If the auditory canal is damaged, the patient develops excessive salivation. The patient does not smell, and the smell disappears.
An increase in the neoplasm leads to the fact that the nerves of the cerebellopontine angle are pinched and then additional clinical signs develop:
- the voice becomes quieter or disappears;
- during a conversation, the timbre may change;
- swallowing function impaired.
When the cerebellum is compressed by a tumor, the following symptoms appear:
- arms and legs are weakened and move with difficulty;
- it seems that the patient is in slow motion cinema, so he moves;
- the tips of the hands begin to tremble;
- when trying to get something, the patient misses;
- eyeballs move spontaneously.
Diagnostics
The examination helps to identify the source of the ailment and prescribe adequate treatment. Also, the diagnosis is designed to exclude other diseases with similar symptoms, such as damage to the cerebellar angle.
Diagnosis occurs with the use of medical equipment:
- CT scan;
- X-ray
- magnetic resonance imaging;
- angiography.
Treatment
The success of therapeutic measures depends on the period of detection of the disease. Accordingly, the earlier a lesion of the cerebellopontine angle was detected, the greater the chances of restoring the patient’s normal state of health and the performance of damaged organs.
Today, there are two types of treatment:
- Conservative. It is used if the tumor formation has a low growth rate.
- Surgical Surgery is used if the formation is rapidly increasing in size. Additional tools are chemo and radiation therapy.
In this case, surgery is used as a last resort, when other methods have not yielded results. This is due to the fact that in the place of the cerebellopontine angle there are many important areas, the damage of which will lead to the patient's disability or death.
