Charcot–Bouchard aneurysms are

cerebral hemorrhage. Charcot–Bouchard aneurysm rupture might be linked to senile plaque formation in the Alzheimer's disease.[2]

Retinal microaneurysms are seen in conditions like diabetic retinopathy,[3]: 498  HIV related retinal microangiopathy,[3]: 467  sickle cell retinopathy,[3]: 533  idiopathic macular telangiectasia[3]: 601  etc. In diabetic retinopathy, due to breakdown in blood–retinal barrier, microaneurysms may leak plasma constituents into the retina, or it may thrombose.[3]: 498 

Signs and symptoms

Main article: Intracranial hemorrhage § Signs and symptoms

If a Charcot–Bouchard aneurysm ruptures, it will lead to an intracerebral hemorrhage, which can cause

hemorrhagic stroke, typically experienced as a sudden focal paralysis or loss of sensation.[1]

Pathophysiology

Charcot–Bouchard aneurysms are

hemorrhages include the putamen, caudate, thalamus, pons, and cerebellum. [citation needed
]

As with any aneurysm, once formed they have a tendency to expand and eventually rupture, in keeping with the Law of Laplace.[4][5]

Diagnosis

Usually not detected by CT angiography.[5] Retinal microaneurysms can be diagnosed using ophthalmoscopy, fundus photography, FFA, and OCT.[6]

History

Charcot–Bouchard aneurysms are named for the French physicians

Charles-Joseph Bouchard.[7][8] Bouchard discovered these aneurysms during his doctoral research under Charcot.[9]
