Charcot-Bouchard aneurysms are a common cause of stroke. If a Charcot-Bouchard aneurysm ruptures, it will lead to an intracerebral hemorrhage.
- French physicians Jean-Martin Charcot and Charles-Joseph Bouchard described it. Bouchard discovered these aneurysms.
- Charcot-Bouchard aneurysms are associated with chronic hypertension.
- They are usually occur due to involvement of small penetrating (<300 µm) lenticulostriate branch of middle cerebral artery in the basal ganglia, brainstem and midbrain.
They are the reason why hypertensive bleed is most common in Basal Ganglia
