Abstract

Herpes zoster is caused by reactivated varicella-zoster virus (VZV) and characterized by a painful skin rash with vesicles that affects the adjacent dermatomes. Transverse myelitis is a rare complication of VZV infection that may even occur in immunocompetent patients. Here, we report a 60-year-old male patient admitted with right lower-extremity weakness and hypesthesia. Spine magnetic resonance imaging (MRI) revealed transverse myelitis at the C3–C4 and T6 levels. A month prior to admission, the patient was diagnosed with herpes zoster involving the right T2-T4 dermatome. Considering his history of VZV infection, he was treated with intravenous steroids and acyclovir. Eleven days after hospitalization, paraplegia developed to Medical Research Council grade 0/5 despite performing plasmapheresis. MRI confirmed the aggravation of the cord lesion between T4 and T7. Acute transverse myelitis after VZV infection is a rare disease that can cause serious sequelae in immunocompetent patients. Therefore, clinicians should be cautious of this situation.
