Meningiomas are tumors of the meninges (covering of the brain and spinal cord). The tumors usually are slow-growing and benign, but a small percentage of meningiomas become malignant.
Meningiomas are a primary brain tumor, meaning they do not usually metastasize (or spread) from another area, but originate in or on the brain.
Causes and Symptoms of Meningiomas
The cause of primary meningiomas is, as yet, unclear, but risk factors seem to include:
past head radiation
As with many types of tumors found in this area of the body, intense headaches are the most common symptom. Other symptoms include:
weakness, numbness or paralysis in legs or arms (usually on one side)
nausea and vomiting
How Is a Meningioma Diagnosed?
Sophisticated brain scanning technologies such as magnetic resonance imaging (MRI) are used to diagnose meningioma.
Most meningiomas are grade 1, slow growing and benign. Unlike some cancer cells that infiltrate the brain, a grade 1 meningioma remains separate, but can still expand, exerting pressure on the brain.
Grade 2 meningiomas are faster growing and tend to grow into the brain tissue, making them more difficult to treat.
Grade 3 meningiomas are the most aggressive form, and also have a higher recurrence rate.

Craniotomy for Meningioma Meningiomas that have not spread into the brain can often be successfully removed from the dura (a covering of the brain). Your neurosurgeon will remove a small portion of your skull, to access the dura. If possible, all the meningioma will be extracted. Any remaining portions will be treated with other approaches such as stereotactic radiosurgery.
