[A case of multiple cranial nerve palsy with severe dysphagia due to herpes zoster infection].

A case of multiple cranial nerve palsy by herpes zoster was reported. A 79-year-old man showed fever, sore throat, and dysphagia. No vesicle was noted at ear and pharynx. The patient developed, later, left peripheral facial nerve palsy. The cerebrospinal fluid revealed pleocytosis with increased protein. The viral antibody titer of herpes zoster was significantly elevated both in cerebrospinal fluid and in serum. The left facial palsy was slightly improved. But his dysphagia didn't improve during at least 10 months after the onset. Among the cranial nerves, trigeminal and facial nerves are the most commonly affected by herpes zoster. But there are a few cases of the 9th and 10th cranial nerve involvement in the literature. However, dysphagia has rarely been reported in these previous cases, only four cases developed severe dysphagia like the present patient. All of these cases including our case were over sixty years old, while cases with slight dysphagia were under sixty years old. No other differentiating factor is noted between these two groups with regard to sites of vesicles, findings of cerebrospinal fluid and mode of therapy.
