Ependymoma Treatment in Orange County

Ependymoma Newport Beach & Orange County, CAEpendymoma is a type of glioma, which starts in the glial cells. Glial cells support and protect nerve cells in the brain (neurons). Ependymomas develop from ependymal cells, a sub-type of glial cells. These cells line the fluid-filled ventricles or spaces in the brain and the center of the spinal cord. Surgical removal is the best treatment for ependymoma, which is resistant to chemotherapy.


Like other brain tumors, what causes ependymoma is unknown. Although relatively uncommon, the disease occurs within any age group.
Ependymoma symptoms may include:

  • Headaches
  • Seizures
  • Nausea or vomiting
  • Weakness or loss of sensation in the arms and/or legs
  • Speech difficulty
  • Vision problems
  • Loss of memory
  • Personality changes
To help diagnose an ependymoma, Orange County neurosurgeon Robert Louis, MD will thoroughly evaluate your health and symptoms and find a path to the tumor that is least disruptive to your brain, critical nerves, and ability to return to normal functioning. Special imaging of the brain will be required to find confirm and locate the tumor.

Magnetic resonance imaging (MRI): An MRI uses magnetic fields to produce detailed images of the brain. A special dye called a contrast medium is injected into a patient’s vein before the scan to create a clearer picture.

Biopsy: Dr. Louis will perform this technique, which uses a needle guided to the tumor or it can be done during surgery when the surgeon can look at the tumor directly. This process is crucial as it will dictate the best course of treatment and will also give important information about the prognosis.

After diagnostic tests are done, Dr. Louis will review all of the results with you and describe the tumor stage, grade, and best treatment options.

Stereotactic Radiosurgery- Gamma Knife®
Your Orange County neurosurgeon Robert Louis, MD may also treat your ependymoma by using a linear accelerator-based system called stereotactic Gamma Knife® radiosurgery – a painless procedure that delivers hundreds of highly-focused radiation beams to a tumor or lesion within the brain without any surgical incision.
