Abstract

The common causal lesions of pure dysarthria syndrome were known as anterior or posterior internal capsule, genu of internal capsule, adjacent corona radiata, or pons. And there are a few reports showed that bilateral small thalamic infarctions or paravermal cerebellar infarction also caused pure dysarthria. The rostral cerebellum, especially paravermal region is thought to have a major role in coordination of speech. The paravermal region is Intimately connected to caudal red nucleus. We report a patient with acute dysarthria and minlmal contralateral limb ataxia, in whom the causal lesion was in caudal red nucleus and superior part of decussation of brachium conjunctivum.
