Diagnosis:
MRI:
- Infarcts
- Enhancing mass lesion
- Cavernous marlformations
Angiogram/Catheter angiography:
- Stenosis in MCA, ICA
- Can also cause accelerated atherosclerosis in the extracranial internal carotid artery
Treatment:
Depends on presentation:
- Enhancing mass, typically treated with steroids
- Infarcts are treated with antiplatelets, but data is limited
- Extracranial accelerated atherosclerosis is treat with antiplatelets, risk factor control and carotid artery stenting if severe stenosis
