Central nervous system (CNS) tumors in children are a heterogeneous collection of neoplasms ranging from benign (low-grade, World Health Organization (WHO) grades I and II) to malignant (high-grade, WHO grades III and IV) histology and behavior and arising primarily in the brain or spine. These tumors are often referred to collectively as childhood brain tumors, which will be the practice in this chapter. Past studies have variably included children under age 15 years, or sometimes under age 19. |
