lacunar infarct


Also found in: Acronyms.
Any of multiple small cerebral infarcts in the corona radiata, internal capsule, striatum, thalamus, basis pontis, and/or cerebellum, occasionally preceded by transient symptoms, due to occlusion or stenosis of small penetrating branches of the middle and posterior cerebral and median branches of the basilar arteries; resolution of infarcts is characterised by residual 1–3-mm cavities or lacunae, characteristic of long-standing hypertension
