Neurinoma is a benign tumor that affects the seventh pair of cranial nerves (that is, the auditory nerve) and begins to develop from the vestibular part of them.
Neurinoma - Causes of the onset
If we talk about the causes of this disease, then finally determine their modern medicine and could not. With a great deal of probability and certainty, one can only name one reason for the onset of the disease: predisposition, which was inherited.
Also, among indirect causes, the presence of a neurofibromatosis in a patient - that is, a disease that manifests itself in such symptoms and signs as the appearance of fibroids in various parts of the body - is noted.
It is also interesting that neurofibromatosis is also a problem that can be inherited. If the parents had a similar gene, then the probability that the child will be born with the same disease is about fifty percent.
Symptoms of neurinoma
Symptoms and signs of a small neurinoma (up to two centimeters) are the following manifestations:
- The tumor squeezes out a part of the nerve that performs the vestibular function. This symptom causes loss of balance (this occurs in about sixty percent of cases), signs of this are dizziness and instability.
- If the formation has compressed the facial nerve - the face grows numb, tingling of the skin appears on the side where the nerve is clamped.) Also, among the symptoms and signs, doctors note a certain taste disorder.
- If the tumor compresses the cochlear nerve - this in the vast majority of cases will lead to some hearing impairment (about ninety-five percent of cases).
If the disease progresses and its size reaches the size of a walnut, more radical symptoms and signs will appear: almost complete deafness, rapid eye movements, reduced corneal sensitivity (in ninety percent of cases), taste is disturbed.
If the tumor reaches a large size (for example, a hen's egg) - among the symptoms and signs of the disease will be a violation of vision and mental health, a violation of swallowing.
Neurinoma - Diagnosis
In order to diagnose this disease, you need to determine the hearing impairment, that is - to record audiograms. Make MRI and CT, as well as conduct a text that will help to identify nystagmus (electron-histogram).
Neurinoma - Types of the disease
By type of structure, neurinomas are divided into:
- Epileptoid. They are characterized by a dense arrangement of tumor cells with a small number of fibers.
- Angiomatous. Tumors have a variety of cavernous cavities, which are formed due to pathological expansion of blood vessels.
- Xanthomatous. Tumors of this type reveal a lot of xanthochromic cells with a high pigment content.
From the point of view of localization, the most common are neurinoma of the spine, auditory nerve and plantar nerve.
Treatment of neurinoma
Depending on the location, size and type of tumor, the oncologist can prescribe various medical procedures. The most common method of treating neurinoma is surgical.
Neurinoma - Complications
Since this is a benign formation, the removal of neurinoma does not lead to relapse.
Prophylaxis of neurinoma
To date, there are no methods of preventing neurinoma.
