Medulloblastoma, Pineal Germinoma, and Ependymoma
Medulloblastoma is a fast-growing, high-grade tumor that is relatively rare and is located in the cerebellum, the lower rear portion of the brain. Pineal germinoma is a tumor that occurs in the pineal gland, which is near the center of the brain and blocks the brain’s fluid channel. Ependymoma is a tumor that originates in the ependyma, a tissue found in the central nervous system. It lines the ventricles of the brain and the center of the spinal cord. These cancers is are rare in adults, with more cases seen in children.
