If all of the tumor cannot be removed in an operation, a patient may also receive external-beam radiation therapy after surgery. Malignant Meningioma are rare tumors that grow more quickly than other meningiomas. The choroid plexus makes the fluid that fills the ventricles and surrounds the brain and spinal cord. The rapidly growing tumors are more likely to spread to other places in the brain and to the spinal cord. It may come back in the brain or in another part of the body.
Treatment depends on the type of tumor and the initial course of treatment.
Surgery is the most common treatment of adult brain tumors. To take the cancer out of the brain, the doctor will first cut a part of the bone from the skull to get to the brain. This operation is called a craniotomy. After the doctor removes the cancer, the bone will be put back or a piece of metal or fabric will be used to cover the opening of the skull. It is a local therapy that only affects cancer cells in the treated area.
