Also known as microaneurysms.
Charcot–Bouchard aneurysms are aneurysms of the brain vasculature which occur in small blood vessels of less than 300 micrometre diameter.
They are most often located in the lenticulostriate vessels of the basal ganglia and are associated with chronic hypertension.
Charcot–Bouchard aneurysms are a common cause of cerebral hemorrhage.
A rupture of a Charcot–Bouchard aneurysm will lead to an intracerebral hemorrhage, which can cause hemorrhagic stroke.
They are small penetrating blood vessels of the brain, associated with hypertension.
The common artery involved with Charcot-Bouchard aneurysms is the lenticulostriate branch of the middle cerebral artery.
Common locations of hypertensive hemorrhages include the putamen, caudate, thalamus, pons, and cerebellum.
Such small lesions are usually not detected by CT angiography.
