Paroxysmal dysarthria caused by cerebrospinal fluid rhinorrhea.

Cerebrospinal fluid (CSF) rhinorrhea causes the loss of CSF, resulting in a decrease in intracranial pressure and a lack of CSF protection in brain tissue. CSF rhinorrhea may cause impairment of posterior cranial nerves resulting in facial paralysis and vertigo. However, dysarthria caused by involvement of glossopharyngeal nerves and vagus nerves has seldom been reported. Here, we reported a 69-year-old woman who had paroxysmal slurred speech due to CSF rhinorrhea together with paroxysmal facial paralysis.
