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

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

Characteristic mastoid contusion.
- Thought to be associated with vascular Ehlers-Danlos syndrome.
