We herein present a case of 6-year-old female demonstrating atypical Ramsay-Hunt syndrome. She presented with an earache, severe vertigo, and vomiting at onset, and thereafter, herpes zoster oticus appeared. No facial nerve palsy was seen. She was vaccinated for varicella and had no past history of apparent varicella infection. The patient showed positive IgG and negative IgM serum antibodies for varicella-zoster virus (VZV). An analysis of VZV-DNA from the patient's ear lesion using alleric discrimination real-time PCR identified a wild-type strain of VZV. We diagnosed her to have atypical Ramsay-Hunt syndrome caused by reactivation of the VZV. Aciclovir and prednisolone were administered, and she recovered completely. This case indicates that Ramsay-Hunt syndrome could be caused by a VZV infection after vaccination, even though its frequency is low. Ramsay-Hunt syndrome may thus be considered as one of causes of sudden onset vertigo in children.

We report a case of an acute HHV-7 encephalitis involving the nucleus of the VI cranial nerve in an immunocompetent host. The patient was an adult male admitted to our Clinic with headache, diplopia, fever, nausea, vertigo, asthenia and general malaise. PCR for viral and bacterial genomes was run on both serum and cerebral spinal fluid (CSF) after performing lumbar puncture, resulting positive only for HHV-7 DNA on CSF. MRI showed hyperintensity in FLAIR signal in the dorsal pons, in the area of the VI cranial nerve nucleus. Empirical therapy with Acyclovir and Dexamethasone was started at the time of admission and was continued after the microbiology results. After three days of therapy diplopia, fever and other previous clinical manifestations improved and the patient recovered normal sight. Our case report contributes to a better understanding of the presentation, diagnosis and treatment of HHV-7 encephalitis in immunocompetent patients due to reactivation in adult age.
