intracranial arterial calcification

Calcification of the intracranial arteries associated with primary atherosclerosis is more frequent in elderly people.

The prevalence of intracranial artery calcification are:

• internal carotid artery: ~60%
• vertebral artery ~20%
• middle cerebral artery ~5%
• basilar artery  ~5%

Other causes of vascular intracranial calcifications include:

• aneurysm: although patent aneurysms may contain mural calcification, partially or completely thrombosed aneurysms commonly have calcification
• arteriovenous malformation (AVM): may contain dystrophic calcification along the serpentine vessels and within the adjacent parenchyma with a prevalence of 25-30%
• cavernous malformation: is a benign vascular hamartoma that is frequently calcified in a ’’popcorn-ball’’ shape
• calcified cerebral emboli: rare cause of embolic ischemic stroke that may carry a different prognosis to that of stroke caused by other types of emboli
