My daughter died following surgery for removal of an ependymoma brain tumor. Be sure you get treatment at the BEST medical facility in the country by a qualified neurosurgeon, because that will make the difference. My daughter started having headaches at age 13 and was never diagnosed properly by many Dr's. It was only 2 days before her surgery that an MRI was finally done that showed the tumor. She was 21 at the time. Please let me know about your little girl. I pray things turn out good for all of you.
