AB  - SUMMARY: The WHO Classification of Tumors of the Central Nervous System has become the worldwide standard for classifying and grading brain neoplasms. The most recent edition (WHO 2007) introduced a number of significant changes that include both additions and redefinitions or clarifications of existing entities. Eight new neoplasms and 4 new variants were introduced. This article reviews these entities, summarizing both their histology and imaging appearance. Now with more than 3 years of clinical experience following publication of the newest revision, we also ask, “What can the neuroradiologist really say?” Are there imaging findings that could suggest the preoperative diagnosis of a new tumor entity or variant? aCPPatypical choriod plexus papillomaCNScentral nervous systemCPPchoriod plexus papillomaCPCachoriod plexus carcinomaDNETdysembryoplastic neuroepithelial tumorEVNCTextraventricular neurocytomaMBmedulloblastomaMBENmedulloblastoma with extensive nodularityPApilocytic astrocytomaPGNTpapillary glioneuronal tumorPMApilomyxoid astrocytomaPPTIDpineal parenchymal tumor of intermediate differentiationPTPRpapillary tumor of the pineal regionRGNTrosette-forming glioneuronal tumorSCOspindle cell oncocytomaT1C+post-contrast T1-weightedT1WIT1-weighted imagingT2WIT2-weighted imagingWHOWorld Health Organization
