Brainstem Gliomas: Approximately 10% to 15% of childhood brain tumors are brainstem gliomas, which most commonly affect children between the ages of 5 and 10 years. Because of their location, brainstem gliomas may cause sudden dramatic symptoms, such as double vision, clumsiness, difficulty swallowing, and weakness.
Among children, the most common tumor types are: 1  Medulloblastoma: The tumor usually arises in the cerebellum. 2  Grade I or II astrocytoma: In children, this low-grade tumor occurs anywhere in the brain. 3  Ependymoma: The tumor arises from cells that line the ventricles or the central canal of the spinal cord.
