==High-grade astrocytoma with piloid features==
* Frequent in posterior fossa (75%).
* 1-3% of all brain tumors.
* Histology may resemble Glionblastoma or Pleomorphic xanthoastrocytoma.
* Tumor is enriched for piloid cell processes.
* ATRX nuclear loss is frequent.
* Usu. MAPK-pathway alterations + CDKN2A homozygous deletion.
* Distinct methylation profile.
