Brain herniation syndromes

(Redirected from Herniation Syndromes)

Types

Type of brain herniation
  1. Uncal
  2. Central Transtentorial
    • Pinpoint → nonresponsive midpoint pupils
    • Motor weakness → increased tone → flexor, then extensor posturing
  3. Cerebellotonsilar (posterior fossa pressure)
  4. Upward Transtentorial
    • Pinpoint pupils
    • Downward conjugate gaze
  5. Subfalcine herniation (cerebral mass lesion causes medial surface of affected hemisphere to push against rigid falx cerebri, then herniate underneath)
    • Cingulate gyrus most commonly affected
    • Often clinically silent
