Ependymomas are a type of brain tumor that arise from ependymal cells, which line the ventricles of the brain and the central canal of the spinal cord. These tumors can occur in both children and adults, but they are more common in children. Ependymomas can vary in grade, with higher-grade tumors being more aggressive and likely to spread. Symptoms of ependymomas depend on their location and may include headaches, nausea, vomiting, and neurological deficits. Treatment typically involves surgical removal of the tumor, and additional therapies like radiation may be used to reduce the risk of recurrence. Early diagnosis and treatment are crucial for better outcomes.
