Ramsay Hunt syndrome presenting as a cranial polyneuropathy.

Ramsay Hunt syndrome (RHS) is herpes zoster of the facial nerve, frequently associated with VIII cranial nerve involvement, but on rare occasions other cranial nerves are affected as well. We present the case of a 63-year-old woman with RHS with involvement of V, VII, VIII, IX, and XII cranial nerves. The patient showed significant improvement after treatment with acyclovir and prednisolone. RHS should be recognized as a polycranial neuritis characterized by damage to sensory and motor nerves, including the facial nerve and the auditory-vestibular apparatus. Early institution of treatment with antiviral agents may help hasten healing. Involvement of the XIIth cranial nerve has not been reported previously.
