Medulloepitheliomas are fast-growing tumors that usually form in the brain, spinal cord, or nerves just outside the spinal column. ETMR most commonly occur in young children and are fast-growing tumors.

Medulloblastomas are fast-growing tumors that form in brain cells in the cerebellum. Most CNS embryonal tumors are medulloblastomas. The different types of CNS embryonal tumors include: Enlarge Anatomy of the inside of the brain, showing the pineal and pituitary glands, optic nerve, ventricles (with cerebrospinal fluid shown in blue), and other parts of the brain. There are different types of CNS embryonal tumors. The treatment of metastatic brain tumors, which begin in other parts of the body and spread to the brain, is not discussed in this summary. See the PDQ summary on Adult Central Nervous System Tumors Treatment for more information on the treatment of adults. Treatment for adults may be different from treatment for children. For information about the different types of brain and spinal cord tumors, see the PDQ summary on Childhood Brain and Spinal Cord Tumors Treatment Overview.īrain tumors occur in both children and adults. This summary is about the treatment of primary brain tumors (tumors that begin in the brain). Both benign and malignant brain tumors can cause signs or symptoms and need treatment.Īlthough cancer is rare in children, brain tumors are the second most common type of childhood cancer, after leukemia. They rarely spread to other parts of the brain. Benign brain tumors grow and press on nearby areas of the brain. When a tumor grows into or presses on an area of the brain, it may stop that part of the brain from working the way it should. Malignant brain tumors are likely to grow quickly and spread into other parts of the brain. Most of the tumors in children are malignant. Medulloblastoma and other CNS embryonal tumors may be malignant ( cancer) or benign (not cancer).

These tumors tend to spread through the cerebrospinal fluid (CSF) to other parts of the brain and spinal cord. Medulloblastoma and other central nervous system (CNS) embryonal tumors may begin in embryonic (fetal) cells that remain in the brain after birth. Certain factors affect prognosis (chance of recovery) and treatment options.A biopsy may be done to be sure of the diagnosis of medulloblastoma and other CNS embryonal tumors.Tests that examine the brain and spinal cord are used to diagnose childhood medulloblastoma and other CNS embryonal tumors.Signs and symptoms of childhood medulloblastoma and other CNS embryonal tumors depend on the child's age and where the tumor is.Certain genetic conditions increase the risk of childhood medulloblastoma and other CNS embryonal tumors.Pineoblastomas form in cells of the pineal gland.
