MRI axial images - (Left) Flair axial; (Right) Diffusion weighted. Note the ischemic stroke seen in the diffusion weighted image in the region of the right thalamus. This type of stroke is caused by occlusion of the deep perforating blood vessels (also known as small vessel disease or lacunar strokes). Small vessel disease is most commonly associated with hypertension and diabetes. There are several classic lacunar syndromes, including pure motor hemiparesis, ataxic hemiparesis, clumsy hand-dysarthria (lesions either in the internal capsule or basis pontis) and pure sensory stroke (lesion in the thalamus).
