Intracranial hematomas are bad stuff that keep neurosurgeons busy. They are usually diagnosed by imaging (CT head).
Classification
- 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]
- Anterior communicating artery (ACA) - most common.
- Middle cerebral artery (MCA) - second most common.
- Classically caused by aneuryms:[2]
- Intracerebral hemorrhage.
- > 60 ml at presentation (assessed via CT scan) assoc. with > 90% 30 day mortality.[3]
Subarachnoid hemorrhage
- Abbreviated SAH.
Traumatic SAH
- May have a characteristic mastoid contusion.
- May be associated with vascular Ehlers-Danlos syndrome.
