Jul 24, 2023 · Lenticulostriate Infarct. Infarction of the deep, perforating lenticulostriate branches of the MCA also is most likely caused by an embolism of cardiac origin. Lenticulostriate vessels tend to result in lacunar infarcts, which may be differentiated from those above due to lack of cortical involvement.
