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
e xtracranial (transcalvarial) herniation
paradoxical brain herniation

Aetiology

Any intracranial mass can have this effect:

intracranial haemorrhage
cerebral swelling
- cerebral infarction
- peritumoural or periabscess oedema
tumours
cerebral abscess
