Causes
The exact cause is not known. Genes may play a role.
Risk Factors
Meningiomas are more common in women, older adults, and people who are Black.
Other things that may raise the risk are:
- Having a parent, sibling, or child with meningioma
- Having neurofibromatosis type 2 (NF2)
- Exposure to radiation
Symptoms
Some people may not have symptoms. Sometimes a tumor can press on the brain and spinal cord. Some common symptoms may be:
- Seizures
- Headaches
- Changes in behavior
- Changes in vision, smell, or hearing
- Problems speaking, writing, and understanding language
- Nausea or vomiting
There may also be other problems depending on where the tumor is located.

Images may be taken to look for tumors. This can be done with:
The tumor may be taken out to confirm the diagnosis.
Treatment
Treatment will depend on the size of the tumor and where it is. A person's age and overall health will also play a role.
People who do not have symptoms may only need to have the tumor watched for changes. Others may need:
Surgery
Surgery may be done if the tumor is getting larger or causing problems. The tumor and possibly some tissue around it will be removed.
Radiation Therapy
Radiation therapy is used to kill cancer cells and stop the tumor from growing. It may be an option for people who cannot have surgery. It may also be used after surgery has been done.
Chemotherapy
Chemotherapy uses drugs to kill cancer cells. It may be an option for people who have not been helped by other methods.
Prevention
Meningiomas cannot be prevented.
