Meningioma

Meningioma is the most common type of primary brain tumor in adults that develops in the meninges, one of the protective layers around the brain and spinal cord. The meninges consist of the dura mater, the arachnoid membrane, and the pia mater, which is right below the skin and skull. Because the meninges cover the entire brain and spinal column, slow-growing meningioma can develop almost anywhere. As it grows, it creates pressure against the brain nerves, tissue and blood vessels in the surrounding areas and cause symptoms. Meningioma occur more often in women more than in men.

If you are suffering from any cranial or brain conditions, we urge you to see our brain specialists at ONE® Brain & Spine Center® for consultation so we may help alleviate your pain and improve your quality of life. Call (949) 383-4190 to schedule an appointment.

It is still not known what alters some cells in your meninges to make them multiply out of control, leading to a meningioma tumor. Some research and evidence suggest that exposure to radiation for treatmeant of another cancer or other conditions may increase the risk of developing a meningioma.

Symptoms of a meningioma begin gradually and may be very subtle at first. Depending on the size and where in the brain the tumor is situated, signs and symptoms may include:

  • Blurry or double vision
  • Worsening headache
  • Seizures
  • Weakness in the arms and legs
  • Memory loss
  • Loss of smell
  • Patients with any neurological symptoms will be given complete examination, including personal and family health history, neurologic function tests, physical exam, tests of vision, and reflexes. If a tumor is suspected, the patient will have imaging tests so the Southern California neurosurgeons can look into the brain for any abnormality. Meningioma show evidence of a dura tail and indentation of the brain. These tests may include:

    Magnetic Resonance Imaging (MRI) – MRI shows the soft tissues of the body and gives clearer picture of the brain.
    Computerized Tomography (CT Scan)- Combined CT scan to see detailed image of the brain.
    Angiography – A procedure in which a blood sample is checked to measure the amounts of certain hormones released into the blood by organs and tissues in the body.
    Biopsy- Minimally invasive nature of fine needle aspiration biopsy may be required to confirm meningioma. diagnosis.

    The experienced team of neurologists at ONE® Brain & Spine Center®, Southern California’s leading center for brain and spine, evaluates each patient and recommends an individualized treatment plan. The usual treatment for meningioma is surgical removal, but a treatment plan may include radiation, stereotactic radiosurgery, or medications. When a meningioma is malignant, radiation therapy may help eradicate cancer cells left behind after surgery. Your Southern California neurosurgeon, Robert Louis, MD, performs minimally invasive procedure to surgically remove the tumor.

    Minimally Invasive Surgical Treatments

    • Endoscopic Transsphenoidal Surgery- The endoscopic transsphenoidal surgical procedure uses a light called endoscope inserted into the nostril and sphenoid sinus to access and remove tumors. The term transsphenoidal literally means “through the sphenoid sinus.”
    • Supraorbital Eyebrow Craniotomy- The supraorbital craniotomy uses an incision within the eyebrow, to create a small opening above the orbit.
    • Retromastoid Approach- The retromastoid approach is performed through an incision behind the ear and a small bony opening that allows access to the back portion of the brain where the brainstem and nerves are located.
    • Stereotactic Radiosurgery-
    • Stereotactic radiosurgery such as Gamma Knife® send out highly focused beams of radiation aimed at a tumor from multiple angles, an advanced specialty that is best performed by highly trained and experienced neurosurgeon.
