acquired intracranial herniation

Brain herniation, also referred to as acquired intracranial herniation, refers to shift of brain tissue from its normal location, into an adjacent space as a result of mass effect. It is a life-threatening condition that requires prompt diagnosis.

Pathology

There are a number of different patterns of brain herniation that describe the type of herniation occurring:

• subfalcine herniation
• transalar herniation: ascending and descending
• transtentorial herniation
  • downward: uncal herniation and central herniation
  • upward: ascending transtentorial herniation
• tonsillar herniation
• extracranial (transcalvarial) herniation
• paradoxical brain herniation

Etiology

Any intracranial mass can have this effect:

• intracranial hemorrhage
  • extradural hemorrhage
  • subdural hemorrhage
  • intracerebral hemorrhage
• cerebral swelling
  • cerebral infarction
  • peritumoural or periabscess edema
• tumors
  • brain tumors
  • meningioma
  • base of skull tumors
  • suprasellar tumors
• cerebral abscess
