Coma Due to Cerebral Mass Lesions : How To Remember Easily ?

  • C – Compartments in the cranium restrict displacement of brain tissue.
  • E – External compression of brain tissue causes herniation.
  • R – Specific clinical features are characteristic of herniation configurations.
  • E – Enlargement of the ipsilateral pupil is a sign of uncal herniation.
  • B – Brainstem displacement leads to a Babinski sign and ipsilateral hemiparesis.
  • R – Resultant brain infarction may occur due to compression of cerebral arteries.
  • A – Anterior and posterior cerebral arteries may be compressed.
  • L – Lateral displacement of the midbrain causes coma.
  • M – Medial temporal gyrus (uncus) impacts the tentorial opening in uncal herniation.
  • A – Accompanying contralateral hemiparesis often occurs with hemispheral lesion.
  • S – Subarachnoid space compression leads to enlargement of the ipsilateral pupil.
