Charcot–Bouchard aneurysm
Medical condition
Charcot–Bouchard aneurysms 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.[1] Charcot–Bouchard aneurysms are a common cause of 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
