Benign meningiomas should not be taken carelessly!


Benign meningiomas should not be taken carelessly, they are also life threatening!

Surgery is the preferred method of treatment. The tumor can be completely removed by surgery to achieve a cure.

Among patients admitted to neurosurgery, meningioma is very common, accounting for 19.2% of intracranial tumors. Although meningiomas are mostly benign, as the tumor grows, it causes significant pressure on the surrounding brain tissue, and intracranial pressure increases. High, central nervous system damage, also life-threatening!


  • What is the disease of meningioma?
  • What should I check?
  • Is meningioma benign or malignant? is it serious?
  • How to treat it, can it be cured?
  • What are the precautions in life…

01 What exactly is meningioma?

There are three layers of membranes between the skull and the brain, from the outside to the inside, the dura mater, arachnoid membrane and pia mater. Cells in the meninges and meningeal spaces (mostly arachnoid cells), these cells are under the action of various tumor-causing factors, and the new organisms formed by local tissue cell proliferation are called meningiomas.


Benign meningiomas should not be taken carelessly


Prevalence population: the disease is more common in adults, less in children, and more women than men.

Prevalence sites: Meningioma originates from arachnoid endothelial cells. Intracranial arachnoid granules and arachnoid villi are more common, which are the most common sites for meningioma. However, meningiomas are widely distributed in the brain, almost all It can happen anywhere.

Cause: The occurrence of meningioma is not a single factor, but may be related to certain internal environmental changes and genetic mutations, or may be related to factors such as head trauma, radiation exposure, and viral infection.


02 What are the symptoms of meningioma?

Most meningiomas are benign tumors with slow growth, long course of disease, different locations, and different symptoms, such as headaches, seizures, vision, visual field, smell or hearing disorders, and limb movement disorders, etc., such as tumors growing on the top of the skull. Headaches and seizures may occur; if it is at the base of the anterior skull, vision loss and sense of smell will usually appear; if it is at the posterior fossa, it may manifest as hearing loss, facial numbness, and unstable walking, etc., but headaches and epilepsy are the top priority in patients Symptoms.

Therefore, do not underestimate chronic headaches or epileptic seizures in adults. You should go to the neurosurgery department of the hospital as soon as possible for early investigation. Do not take painkillers or oral antiepileptic drugs freely for temporary relief, so as not to delay valuable The timing of treatment.



03 What should I check for meningiomas?

Commonly used examinations are head CT and magnetic resonance imaging (MRI), which can diagnose meningioma early.

Head CT: It is widely used and can be used as a preliminary screening. It can also show the relationship between meningiomas and adjacent bone structures, and whether there is calcification.

MRI: It can assist in determining the nature of the tumor, the texture of the meningioma, the relationship with the surrounding blood vessels, and brain edema. The detection rate of smaller meningioma is higher.


04 How should meningioma be treated?

Although most meningiomas are benign tumors, most symptomatic meningiomas require active surgical treatment. As everyone pays more attention to health and advances in imaging examinations, asymptomatic meningiomas are gradually increasing. The following factors should be considered when deciding on the treatment of meningiomas :

  • ⑴ Patients with peritumoral edema should be operated on;
  • (2) Those with space-occupying effect, epilepsy and mental decline should undergo surgery;
  • ⑶The convex surface of the supratentorial brain, parasagittal sinus, parasitic, and intraventricular meningioma should be operated early;
  • ⑷ Skull base meningiomas such as sphenoid crest, sellar tuberosity, olfactory sulcus, and cerebellopontine angle should be operated on;
  • ⑸ If flat meningioma, cavernous sinus meningioma, and clioval meningioma are asymptomatic, surgery is not necessary temporarily.

Surgery is the preferred method of treatment. The tumor can be completely removed by surgery to achieve a cure.
