[Lacunar brain infarct in carotid occlusion].

The etiology of lacunar CCT lesions is controversial. We report a patient with recurrent ischemia in the territory of the right internal carotid artery. CCT initially showed a fresh non-lacunar lesion in the area of the basal ganglia and internal capsule. Subsequently, repeat CCT revealed a singular lacunar defect in the internal capsule. The Doppler sonographic investigations showed an internal carotid artery occlusion. This case supports the hypothesis that an embolic or hemodynamic etiology of the lacunae is possible.
