Lacunar Infarctions Due to Cholesterol Emboli Stroke 22:1440-1444, Laloux,P.&Brucher,J., 1991 See this aricle in Pubmed Article Abstract We describe a 79-year-old patient with a progressive multi-infarct dementia who developed transient motor aphasia and paresis of the right arm.Computed tomography showed lacunar infarcts in the right caudate nucleus,left thalamus,and left putamen,as well as an old right frontal infarction.Neuropathological examination demonstrated no prominent vascular hyalinosis,but did show multiple cholesterol emboli occluding small arteries around lacunar infarcts and leptomeningeal arteries near cortical infarcts.The cholesterol material presumably originated in the extended atheromatous changes along the aortic arch.Our report confirms that lacunes can be caused by cholesterol emboli in some patients.Small cerebral emboli should not be overlooked as a cause of lacunes.
