This tumor is developing from the meninges, this tumor is almost always of benign nature.

Un méningiome est une tumeur méningée qui se forme à partir d’une des trois membranes constituant les méninges et qui se nomme l’arachnoïde. Elle prend racine dans une autre membrane méningée, la dure-mère. Elle est bénigne dans 9 cas sur 10, atypique avec tendance à récidiver dans 9 % des cas (grade II) ou maligne (cancéreuse) dans moins de 1 % des cas (tumeur de grade III).

What does meningioma look like?

Meningioma is mostly a unique tumor, a few millimeters when diagnosed early. Rich in blood vessels, the latter are powered by the meningeal arteries and those coming from the brain fabric.

Généralement, on le trouve sur les hémisphères du cerveau mais la base du crâne ou le cervelet peuvent l’héberger. Selon l’endroit où il se développe, les symptômes varient très sensiblement et son évolution est lente.

Meningioma: What causes?

We know only one factor promoting its appearance, and it is an exposure to ionizing radiation. Other suspected factors?

Des dispositions génétiques héréditaires, les bouleversements hormonaux liés à la grossesse, ou d’autres facteurs hormonaux liés à certains traitements hormonaux par progestatifs.

Meningioma symptoms

The tumor may not cause signs and be discovered only during an examination (scanner or brain MRI) carried out for a completely different reason than its existence.

However, here is what can be manifested without anyone or the other of these signs allow them to be lio to meningioma:

  • diffuse or local headaches, banal or recently appeared and worsening despite analgesics;
  • Disorders of vision, sensitivity, speech, sight, behavior that has occurred recently or recent memory disorders;
  • weakness in arms or legs;
  • perte de l’équilibre et vertiges, perte de l’audition ou de l’odorat ;
  • epilepsy crisis.

As for the diagnosis, it will be made after an MRI or a scanner.

Treatment of meningioma

The fact that its evolution is slow can induce simple medical surveillance.

Surgery

However, surgery can also be essential when the symptoms are felt.

Depending on the size of the tumor, its location and the way it invades the bone, the surgical operation may not allow the total disappearance of the tumor.

Radiotherapy

Treatment by rays, whose mission is to destroy meningioma cells, can also be a solution. After the treatment of such a tumor, monitoring by control MRI is essential.
