Pediatric Brain Tumors. Atypical Patterns and Peculiarities

The purpose of this presentation is not to provide a comprehensive review of pediatric brain tumors, which can easily be obtained elsewhere. Rather, I have elected to focus on a number of issues and peculiarities which, while only rarely dealt with in major books, may represent significant challenges for the neuroradiologist in the everyday clinical practice. Thus, this review will cover (i) diffusely infiltrating tumors; (ii) disseminated low-grade gliomas; (iii) selflimiting tumors; (iv) tumor predisposition syndromes; and (v) medulloblastoma variants.
