We report varicella-zoster virus (VZV) meningitis in a healthy adult woman with no antecedent rash and with hypoglycorrhachia. Cerebrospinal fluid (CSF) examination revealed the presence of VZV DNA, anti-VZV immunoglobulin G (IgG) antibody, and intrathecal production of anti-VZV IgG antibody.Keywords varicella zoster; meningitis; hypoglycorrhachia; PCR; immunocompetent
Case reportA 26-year-old healthy Bhutanese woman developed increasing throbbing bitemporal headache with photophobia, severe nausea, and vomiting over 2 days. She had been afebrile and denied neck stiffness. There was no past history of headache, skin rash, recent insect bite, or contact with individuals with infections. She had chickenpox at age 5 years. She had emigrated from Bhutan 7 years earlier, but had not traveled abroad recently. Her sister had been treated for tuberculosis. She worked currently as a nanny; the children under her care were healthy and had received Varivax months earlier. On examination, the patient was afebrile and had no rash, nuchal rigidity, or abnormal neurological signs.On day 6 after becoming ill, white blood cell (WBC) count and routine blood chemistries, liver enzymes, erythrocyte sedimentation rate (ESR), anti-nuclear antibody, rapid plasma reagin, and human immunodeficiency virus testing were negative. Brain magnetic resonance imaging (MRI) revealed an ill-defined T2 hyperintensity in the right frontal lobe, extending from the cortical surface to the frontal horn of the lateral ventricle without mass effect, consistent with a hamartoma or cortical dysplasia. The cerebrospinal fluid (CSF) contained 331 WBCs, 99%
