Background
Cerebral herniation is the displacement of cerebral matter from its normal location to an adjacent site, secondary to an abnormal increase of the intracranial volume. Several conditions such as tumor growth, haedema, haemorrage can predispose to raise intracranial pressure and consequently determine increase of intracranial volume.
Brain herniation may cause brain pressure necrosis, compress cranial nerves and vessels causing hemorrhage or ischemia, and obstruct the normal circulation of CSF, producing hydrocephalus.
Therefore, each type of hernia may be associated with a specific neurologic syndrome. Consequently, clinical informations are useful for guiding a detailed examination of the potentially involved anatomic structures; furthermore, the patient’s history, current clinical scenario, and specific neurologic syndromes should be considered.
