Presentation Transcript

  1. Palisades and tumors

  2. Lung metastatic tumor in brain

  3. A meningioma at a parasagittal location

  4. Benign meningioma growing underneath the dura

  5. Note compression caused by meningioma in the underlying cerebral hemisphere

  6. Meningioma compressing the pituitary

  7. Giantism can result from pituitary tumors in childhood

  8. Benign ependymoma; note inaccessible site

  9. Cystic astrocytoma of childhood

  10. Glioma with mass effect

  11. Low grade gliomas still have poor prognosis if present in a difficult to remove location

  12. Large brain stem glioma

  13. Cerebral hemisphere glioma; note absence of clear margin

  14. Astrocytoma at low magnification; normal tissue at right

  15. Glioblastoma multiforme

  16. GBM: note necrosis, hemorrhage

  17. Note palisading effect around necrotic region

  18. Two models for the formation of pseudo-palisades in GBM

  19. Palisading cells surrounding necrosis are typical of GBM

  20. Model for formation of palisades
