We report the case of an 82-year-old male with subacute sensorimotor neuropathy associated with Epstein-Barr virus (EBV) infection, who presented with diplopia followed by gait disturbance due to limb weakness. Pathological findings of a biopsied cervical lymph node showed a high frequency of EBV-positive cells. EBV-DNA was detected in blood. A nerve conduction study suggested a mixture of axonal damage and demyelination. Brain MRI showed multiple microbleeds in cerebellar cortices, but cerebrospinal fluid EBV-PCR was negative, suggesting bleeding due to EBVrelated vasculitis. Corticosteroid therapy improved the neurological symptoms and the patient was able to walk independently four months later. The main pathogenesis of the neuropathy in this case is likely to be a mixture of vasculitic neuropathy and immune-mediated demyelinating neuropathy, which are considered to be due to EBV reactivation.
