Cerebral Herniation Syndromes
Cerebral herniation syndromes are medical emergencies caused by displacement of the brain across hard structures in the skull. Acute and/or asymmetric increases in intracranial pressure, as seen with hemorrhage into a tumor or obstruction of cerebrospinal fluid (CSF) flow, are most likely to cause herniation. Ill-timed lumbar puncture may also cause brain shifts by producing a pressure gradient. The syndromes evolve rapidly, over hours, and are characterized clinically by the following symptoms:
Treatment is designed to reduce intracranial pressure through hyperventilation, steroids, osmotic agents, and surgery.
Pupillary and oculomotor signs
