  2. Clinical Impression MENINGIOMA

  3. Meningioma • Second most common primary tumor • 15% of all primary intracranial tumors • Mostly benign tumor • Origin: arachnoidal (meningothelial cap) cells • particular from the arachnoidvilli • Women:Men (2:1) • Peak Age Incidence: 60th & 70th decades • Vascular Endothelial Growth Factor • Highly vascular, prominent surrounding edema

  4. Etiology of Meningioma • Familial • Truncating mutations in the neurofibromatosis 2 gene (merlin) on chromosome 22q • Radiation Therapy • Previous Head Trauma • Estrogen and Progesterone receptors

  5. WHO Classification of Meningioma

  6. Histological Classification of Meningioma

  7. Clinical Manifestations of Meningioma • Asymptomatic, Incidental finding • Irritation of the underlying cortex  Seizures • Compression of the brain Localized or Non-specific headaches, Focal or Generalized Cerebral Dysfunction • Compression of the cranial nerves  Focal Neurologic Deficits • Erosion, Invasion or Hyperostosis of Cranial bones • Narrowing, Occlusion of important cerebral arteries Transient ischemic attack (TIA)–like episodes or as stroke

  8. Sites of Meningioma
