neuroma - a tumor growing from support cells of the nervous tissue (Schwann cells) that form the myelin sheath and accelerate the transmission of nerve impulses.Tumors of this type are benign in nature, may be located in different regions of the nervous tissue, but most are found in the auditory nerve.The disease mainly affects people in middle-aged and older women suffer from it more often than men.Usually the treatment is carried out neuroma surgically and very successfully.Since this is a benign education, removal of neuroma does not lead to relapse.
Initially, the disease may develop asymptomatic, but eventually begins to disrupt the blood supply to the nerve tissue and squeeze it, leading to dangerous complications.If in any doubt, the doctor prescribes testing and immediate treatment of neuromas, including surgically.
neuroma Symptoms depend on its localization.For example, if the tumor
When acoustic neuroma 95% of patients complain of hearing loss, 70% of tinnitus, 65% on the coordination of movements.Often these symptoms are accompanied by headache, numbness and weakness of the face, nausea and vomiting, diplopia, ear pain, and changes in taste.Upon closer examination, the doctor discovers a variety of movement disorders of the eyeball, swelling, loss of facial sensitivity, weakness of facial muscles and other symptoms.In advanced cases of hydrocephalus and unobtrusive facial paralysis can occur.
When neuroma patient has spinal dysfunction in an area under the responsibility of the damaged section of nerve tissue.The main symptoms neuromas - paralysis, paresis, decreased sensitivity.This so-called radicular disease, whose support is experiencing long-term pain.
When skin neuroma (a rare disease) tumor emerges as a distinct disease tubercle.
Externally, the tumor resembles a tight knot round or irregular shape with uneven surface, its color depends on the blood supply to the nerve area, for example, if venous congestion zone, the color will be bluish.Usually the tumor is enclosed in a capsule of connective tissue and neuroma removal is very successful.
Style neuroma structure divided into:
- epileptic.They are characterized by dense arrangement of tumor cells with small amounts of fibers.
- angiomatous.Tumors have many cavernous cavities, which are formed due to abnormal dilatation.
- Ksantomatoznye.Tumors of this type exhibit ksantohromnyh plurality of cells with a high content of pigment.
In terms of localization, the most common are spinal neuroma, auditory nerve and plantar nerve.
In clinical practice, acoustic neuroma (or as it is also called vestibular schwannoma) occurs in one person in 100 thousand people, and yet, it is one of the most common tumor diseases.Benign education is growing at a rate of 1 to 2 mm per year, but in rare cases may increase in a year and by 30 mm, putting pressure on the cerebellum, brain stem, and even hitting the face, and lower cranial trigeminal nerve.Acoustic neuroma is a one-way (usually manifests itself in 40-50 years) or bilateral (can even be a 20-year-olds).Almost always accompanied by a characteristic symptom of the disease - the ringing noise in the ears or hearing loss, so any suspicion of neurinoma of the auditory nerve of the patient sent for MRI of the head.
plantar nerve neuroma of the foot, or Morton's disease usually affects the area between the third and fourth toes, at least - between the second and third.The main cause of the disease - mechanical damage to the foot.For example, it may be cross-flat, acute trauma, hematoma, chronic infections, fractures of metatarsals or tight and narrow shoes.Against the background of these factors can occur in nerve thickening and when the surrounding bone and ligaments start painful squeeze it in the area of damage may develop inflammation.Symptoms of Morton's neuroma is very characteristic: it all starts with the legs numbness and aching pain, patients complain of burning, tingling and discomfort in the toes, foreign body sensation.As the growth of the tumor pain intensifies.As in the case of acoustic neuroma, the disease diagnosed by MRI.
spinal neuromas formed in Schwann cells in the peripheral, spinal and cranial nerves.The share of the disease accounts for nearly 20% of all primary spinal tumors.Characteristically, the disease affects women of middle-aged and older, but in the malignant form is not reborn.The tumor is progressing on the roots of the spinal cord nerves, mainly in the neck and chest area, at least in the lumbar.In the cervical region of the spine neuroma can "go" through the intervertebral holes, this pathology is also called the "hourglass".The mediastinal tumor area can take a malignant character.Be that as it may, the main symptom of spinal neuromas - radicular pain, the main risk in addition to the pain and the risk of malignant transformation - bone changes, which can be fixed with the help of spondylography.
Depending on the location, size and type of cancer, the oncologist can prescribe various medical treatments.The most common method of treating neuroma - surgical.Removal of neuromas at an early stage may minimally invasive techniques to the conservation of almost all functions, for example, possible to preserve hearing, if the tumor is not larger than 2 cm.
Radiological treatment neuroma is recommended for older people, if surgery is not possible, or if the patient refusesoperation.The method allows to control the tumor growth, but only if it does not exceed 3 cm.
conservative method does not require the removal of neuroma.Instead, the doctor prescribes a diuretic in combination with corticosteroids and drugs to improve cerebral circulation.
In the case of the slow growth of the tumor or severe comorbidities doctor can apply the tactics of waiting, hold regular MRI and CT scan, and then apply the bypass surgery.
When immature malignant tumor, or in the case where removal of neuroma surgically impossible, comprehensive radiation and chemotherapy.
