Charcot–Bouchard aneurysms (also known as miliary aneurysms or microaneurysms) are aneurysms of the brain vasculature which occur in small blood vessels (less than 300 micrometre diameter). Charcot–Bouchard aneurysms 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.
Signs and symptoms
Charcot–Bouchard aneurysms are aneurysms in the small penetrating blood vessels of the brainstem and midbrain. They are associated with hypertension. The common artery involved is the lenticulostriate branch of the middle cerebral artery. Common locations of hypertensive hemorrhages include the putamen, caudate, thalamus, pons, and cerebellum.
Charcot–Bouchard aneurysms are named for the French physicians Jean-Martin Charcot and Charles-Joseph Bouchard. It was Bouchard who discovered these aneurysms during his doctoral research under Charcot.
