Orofacial Dyskinesia and Intractable Hiccups in a Patient with Varicella-zoster Virus Encephalomyelitis.

A 73-year-old Japanese man with diabetic complications presented with involuntary lip movements and long-lasting hiccups after developing zoster rash. Magnetic resonance imaging revealed lesions involving the medial temporal lobe and C1 level of the spinal cord. Varicella-zoster virus (VZV) encephalomyelitis was diagnosed. We considered attributing the orofacial dyskinesia, a very rare symptom of VZV central nervous system (CNS) complications, to the temporal lobe lesion. Although the culprit lesion for the hiccups was unclear, further examinations may have clarified this issue. As immunocompromised patients with herpes zoster may develop CNS complications with a wide variety of symptoms, special care is needed.
