====== Circumscribed astrocytic gliomas ======

The [[World Health Organization Classification of Tumors of the Central Nervous System 2021]], also known as WHO 5th edition, introduces substantial changes, especially within the [[glioma]] category, and separates adult-type and pediatric-type glial tumors into different categories for the first time. In addition, another category of glial tumors, "[[Circumscribed Astrocytic Gliomas]]" was also created. This group includes [[pilocytic astrocytoma]], [[pleomorphic xanthoastrocytoma]], [[subependymal giant cell astrocytoma]], [[chordoid glioma]], [[astroblastoma]], and the highly nebulous novel entity high-grade astrocytoma with piloid features
