Medulloblastoma is a common type of primary brain cancer in children. It originates in the part of the brain that is towards the back and the bottom, on the floor of the skull, in the cerebellum, or posterior fossa. Medulloblastomas are invasive, rapidly growing tumors that, unlike most brain tumors, spread through the cerebrospinal fluid and frequently metastasize to different locations along the surface of the brain and spinal cord. Metastasis all the way down to the cauda equina at the base of the spinal cord is termed "drop metastasis".
In the present book, twelve typical literatures about pediatric medulloblastoma published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on pediatric medulloblastoma. We hope this book can demonstrate advances in pediatric medulloblastoma as well as give references to the researchers, students and other related people.
