Tentorial herniation:
• Occurs when a mass lesion makes one cerebralhemisphere too
large for its compartment and cause the Infero-medial part of the cerebral hemisphere to bepushed
through the tentorial hiatus ( which separates thecerebrum from the cerebellum)
• The increased pressure causes vomiting
• Deterioration of consciousness occurs due todisturbance of
the reticular formation
• Compression on the third nerve results in dilated
pupil,ocular palsy and ptosis
• Results in coning with the whole brainstem beingpushed
downward. This interfere with the vital functionsof respiration (controlled by
medulla oblongata)compression of the pyramidal fibres result in hemiparesis
