- Etiology: trauma, anticoagulation, aneurysm, vascular malformation, vasculitis
- Imaging: blood within cerebral parenchyma, if etiology is uncertain perform MRI and MRA or CTA to look for vascular causes
- Complications: herniation
- Treatment: evacuation of clot
- Imaging evolution of intracerebral hemorrhage evolution on MRI:
— Note: this is most commonly used to date subdural hematomas
