      • Contre coup injuries 
  2. Paediatric Infratentorial Tumours (0-2 yrs) 
    • Atypical teratoid/rhabdoid tumour (ATRT) 
      • Midline, calcs, heterogeneous (similar to medulloblastoma) 
    • Embryonal tumours with multilayered rosettes (ETMR) -> previously PNETs (RARE) 
      • Females, cystic/calcs, patchy enhancement
  3. Paediatric Infratentorial Tumours (4-11yrs) 
    • Medulloblastoma (midline) 
      • Look for leptomeningeal spread/drop mets
      • Heterogeneous, cystic, calcification 
    • Ependymoma (midline) 
      • Squeezes into foramina 
      • Less diffusion than medulloblastoma 
    • Pilocytic astrocytoma (midline usually) 
      • Can be hemispheric 
      • Cystic with enhancing mural nodule (cyst wall enhancement also) 
    • Brainstem glioma 
      • Hydrocephalus and cranial nerve palsies 
    • Haemangioblastoma (hemispheric) 
      • Hx of VHL
      • NO CALCS
      • Well-demarcated, homogenous, cyst w non-enhancing walls and vividly enhancing mural nodule 
      • Flow voids (serpentine) 
  4. Adult Supratentorial Tumours - Intra-Axial 
    • Metastases (MOST COMMON) 
    • Haemangioblastoma 
      • Most common primary brain tumour in posterior fossa 
    • Astrocytomas, medulloblastomas, ependymomas (younger adults)
    • Lymphoma 
    • Lipoma 
  5. Adult Supratentorial Tumours - Extra-Axial
