Intracranial hematomas are bad stuff that keep neurosurgeons busy. They are usually diagnosed by imaging (CT head).

Classification

  1. Epidural hemorrhage (extradural hemorrhage).
    • Patient may have lucid interval.[1]
    • Middle meningeal artery.
    • Radiology: biconvex.
  2. Subdural hemorrhage
    • Damaged bridging veins: subdural space between the dura and arachnoid mater.
    • Radiology: crescent shape.
  3. Subarachnoid hemorrhage.
    • Classically caused by aneuryms:[2]
      1. Anterior communicating artery (ACA) - most common.
      2. Middle cerebral artery (MCA) - second most common.
  4. Intracerebral hemorrhage.
    • > 60 ml at presentation (assessed via CT scan) assoc. with > 90% 30 day mortality.[3]
