  • Summary

    • Intracranial hemorrhage (ICH) occurs when blood occupies space within the calvarium. ICH irritates brain parenchyma and impairs outflow of cerebral spinal fluid (CSF) from the dural sinus venous network, which raises intracranial pressure (ICP) with a resultant decrease in cerebral perfusion.

    • ICH types are defined by the location of the bleeding: intracerebral (within the parenchyma), epidural (between the skull and the dura), subdural (between the dura and arachnoid membrane) and subarachnoid (between arachnoid membrane and pia mater).

    • The skull is inelastic, so blood accumulation increases intracranial pressure.
