  2. 2. The Normal CSF FlowThe Normal CSF Flow
  3. 3. HydrocephalusHydrocephalusAbnormal dilatation of the cerebralventricular systemHydrocephalus should be differentiated fromdisorders producing ventricular enlargementsecondary to cerebral atrophy.Classified into :1. Communicating Hydrocephalus2. Non communicating Hydrocephalus
  4. 4. Characterisics of HydrocephalusCharacterisics of HydrocephalusVentricular enlargement disproportionate tothe degree of sulcal wideningEnlagement of temporal hornePeriventricular fluid 2ry to transependymalCSF permeationEnlarged 3rdventricle with large suprapinealand chiasmatic recesesIn children < 2 years the head circumferenceis often the best distinguishing featurebetween hydrocephalus and atrophy.

  6. 6. Subependymal CSFSubependymal CSFpermeationpermeation
  7. 7. Non-Communicating HydrocephalusNon-Communicating Hydrocephalus(Intraventricular obstruction)(Intraventricular obstruction)Ventricular dilatation caused byintraventricular obstruction at or above thethe outlet foramina of the 4thventricleCauses:1. Lateral ventricle2. Foramen of Monro3. 3rdventricle4. Aqueduct of sylvius5. 4thventricle
  8. 8. Lateral Ventriclar causes:Lateral Ventriclar causes:1. Intrinsic tumor: ependymoma2. Ventriculitis: due to intraventricularadhesions3. Extraventricular Tumour: mass effectfrom large parenchymal mass
  9. 9. Ventriculitis case 1 Ventriculitis case 2
  10. 10. Neuroepithelial Cyst
  11. 11. Causes of Thid Ventricle Obstruction:Causes of Thid Ventricle Obstruction:1. Intraventricular Tumor2. Extraventricular tumour : Pituitaryadenoma , craniopharyngioma,arachnoid cyst.
