Ependymoma: Answers to Common Questions
1. What are the early symptoms of ependymoma?
Intraventricular ependymomas can cause symptoms of increased intracranial pressure—such as headache, nausea, vomiting, and blurred vision—as well as gait instability and neck pain.
2. How are ependymomas graded?
Ependymomas are classified as WHO Grade I–III.Grade I tumors, such as myxopapillary ependymoma, grow slowly.Grade II represents the common type of ependymoma.
3. What are the surgical treatment methods for ependymoma?
Microsurgery is the primary treatment for ependymomas.Total resection is the surgical goal, as it yields the best long-term outcomes.Intraoperative neurophysiological monitoring helps preserve neurological function.
4. What is minimally invasive treatment for ependymoma?
For small intraventricular ependymomas, neuroendoscopic surgery via transnasal or intraventricular approaches allows for tumor removal without craniotomy.Stereotactic radiotherapy is suitable for small residual or recurrent lesions.
5. Why is radiotherapy needed after ependymoma surgery?
Postoperative radiotherapy is required for anaplastic ependymomas and incompletely resected tumors.Craniospinal irradiation is indicated for cases with cerebrospinal fluid (CSF) dissemination.Localized radiotherapy can minimize damage to surrounding normal tissues.
6. How effective is chemotherapy for ependymoma?
Conventional chemotherapy has limited efficacy against ependymoma and is mainly used to delay radiotherapy in infants or for patients with recurrent disease.Certain chemotherapy regimens may be used as adjuvant therapy.
7. How to follow up after ependymoma treatment?
Long-term, regular MRI follow-ups are required postoperatively to monitor for recurrence.Whole-spine MRI is performed to rule out dissemination.Monitor for changes in neurological function, such as pain or limb weakness.
