ABSTRACT
We describe a case presenting with facial and hypoglossal nerve paresis due to cortical cerebral infarction. A 54-year-old man visited our hospital complaining of sudden episode of dysarthria and facial paresis. Neurological findings revealed tongue deviation to the left and left facial paresis with forehead wrinkling while neither limb paralysis nor sensory impairment was observed. Head CT performed on day 3 after onset revealed a cortical infarction in the right prefrontal gyrus. Symptoms gradually improved with medical management. This patient had isolated facial and hypoglossal nerve paresis without other neurological symptoms. Patients with mild paresis of cranial nerves should be diagnosed carefully, because their paresis could be supranuclear type.
