Meningeal tumor

Meningeal tumor's disease overview

Meningioma is the most common benign intracranial tumor. The tumor originates from the hat cells in the spider film - a thin layer like a spider web covered with brain parenchyma and spinal cord. The meninges include: spider membrane, soft membrane and epidural. In which the spider film is one of the three meninges covering the brain and spinal cord.

Is meningeal tumor dangerous ? Most of the brain tumors are benign but they can develop to a very large size when detected, and in special positions can cause large nerve function, life -threatening.

Meningococcal tumor accounts for about 34% of primary tumors in the brain, usually occurring at the age of 30-70. Children have less meningitis than adults. The male/female ratio is about 1/2. In particular, the spine meningeal tumor occurs 10 times in women compared to men. However, the percentage of malignant meninges occurs more than 3 times more than in men.

Causes of Meningeal tumor's disease

Causes of meninges tumors are currently not clearly defined. Some risk factors of the disease include:

Radioactive exposure: Exposure to high -dose ionizing radiation has been shown to be at risk of meningitis. Neurology is associated with higher meningitis rates

Race: Black people are at higher risk of meninges than white people.

Symptoms of Meningeal tumor's disease

Meningioma grows quite slowly, so there is often no signs until the size is quite large. Symptoms of meninges tumor related to tumor size and position of tumor.

Some common signs:

Headache: The headache increases gradually, usually starting in one position then spread throughout the head. The patient then no longer responded to an analgesic pills

epilepsy: Local convulsions 1 part (1 hand, 1 leg) or whole. In severe cases, the patient may fall into a state of epilepsy longer than 30 minutes. > Vomiting, nausea: usually vomiting, not related to meals, after vomiting does not relieve headaches Li>

tinnitus, unable to hear

Some symptoms related to the tumor position such as:

sickle: impaired argument and memorization function. When the tumor is located near the middle line, the patient tends to weaken lower limb, numbness or seizures

Hemisphere : convulsions, headaches, weakness

Butterfly bone: The impact of vision, loss of feeling or moving on the face. Smell the smell of tumor pinching the smell of nerves. When a large development tumor can affect vision due to pinched nervous strings

Yen Yen hole: vision, due to insertion System or nervous interference Li> In ventricular brain: Cerebrospinal fluid retention, leading to increased intracranial pressure: headache, vomiting, mental and visual dysfunction

In the drive t: increased eye pressure, convex eyes, risk of vision loss

spine : back pain, pain due to Nervous compression

People at risk for Meningeal tumor's disease

Meningioma occurs more in women

There is a relationship between meningitis and breast cancer

There is a relationship between pregnancy, The menstrual cycle and the development of meningitis

Prevention of Meningeal tumor's disease

There is no specific measures to prevent meninges

Should go to a neuroscientist when there are suspicious neurological signs

Patients with multiple nerve yarns should go to the examination periodically every 6-12 months. Li>

It is important to eat and drink daily.

Diagnostic measures for Meningeal tumor's disease

Diagnosis of meningeal tumors is quite difficult because most meningeal tumors grow slowly and most of them are only seen in adults, so the symptoms are unclear, causing the patient/doctor to think are normal signs of age. Some symptoms accompanied by meninges can also be caused by other diseases. Li>

Computerized tomography (CT) or magnetic resonance imaging (MRI) helps to evaluate relatively accurately about the characteristics of the tumor such as the position, size, quantity, complications of the tumor causing Such as ventricular dilatation, brain edema. /p>

Meningeal tumor's disease treatments

Main meningitis treatments include: surgery and radiation, chemicals rarely applied.

Surgery

is a method of removing tumors and preserving healthy tissue around. This is the main method in the treatment of meningeal tumors. The technique needs to be supplemented with radiation and chemicals

can cause selective vascular obstruction before surgery to reduce the risk of bleeding during and after surgery

The meninges are done by opening the skull and taking tumors under the microsurgical glass. Modernly used (microsurgical glass) and facilities conducted. Abnormal brain.

Indications in case the tumor cannot be effectively treated by surgery.

Radiotherapy outside the standard : Use a variety of rays to reduce the dose to the normal structures nearby

proton rays: Proton beams are directed directly into the tumor, so normal cells besides tumor is less damaged

stereoscopic radiation (such as gamma Knife, Novalis, Cyberknife): is a technique of converging multiple beams into a fixed target, less influencing Go to the neighboring tissue

Chemicals:

Use chemical drugs to kill tumor cells.

The drug often works to prevent the ability to multiply and divide the cells

Symptomatic treatment:

corticosteroids: Reducing brain edema should reduce symptoms of headache, nausea

Anti -epilepsy drugs: Indication for patients with epilepsy symptoms

Conducting abdominal ventricles: indicated in case of increased intracranial pressure.
