Normal perfusion territories in a patient with a lacunar infarction Images Lacunar infarcts are small infarcts in the deeper parts of the brain. Lacunar infarcts are small (<15 mm) infarcts in the distal distribution of deep penetrating vessels (lenticulostriate, thalamoperforating, and pontine perforating . internal capsule infarct. ataxic hemiparesis syndrome: MCA perforators or basilar artery perforators. lacunar infarct · lacunar stroke syndromes. thalamic infarct.
