Ependymomas Found in the infratentorial region about 65% of the time, and represent 10% of all childhood brain tumors. These tumors arise from ependymal cells in the ventricles and spinal column. Initial signs and symptoms relate to increased intracranial pressure in posterior fossa ependymomas. Medulloblastoma Infiltrate the floor or lateral wall of the fourth ventricle and extend into the cavity. These are fast growing tumors and they may ...
