Intracranial arterial calcification

Last revised by Henry Knipe on 20 Jun 2017

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

The prevalence of intracranial artery calcification are:

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
