title: Transient hemiglossal denervation during acute internal capsule infarct in the setting of dysarthria-clumsy hand syndrome.
abstract: A case of MR imaging-documented transient unilateral tongue denervation presenting during acute internal capsule infarction is described. Understanding the corticolingual pathway innervation of the hypoglossal nucleus is essential for explaining these findings. Awareness of the findings in this case will facilitate appropriate diagnosis, provide neuroanatomic explanation, and prevent misdiagnosis.
