itor Title: Varicella zoster virus reactivation antedating ipsilateral brainstem stroke Authors: Giuliana Galassi1, Maurilio Genovese2, Marisa Meacci3, Marcella Malagoli2 Affiliations: 1Department of Biomedical, Metabolic, Neural Sciences, University Hospital of Modena, Italy, 2Neuroradiology Service, University Hospital of Modena, Italy, 3Department of Laboratory Medicine and Patholgy, Microbiology and Virology Unit, University Hospital of Modena, Italy Corresponding Author: Giuliana Galassi, MD, Department of Biomedical, Metabolic, Neural Sciences, University Hospital of Modena, Via P.

Unifocal large vessel infarcts may follow zoster in the trigeminal or cervical distribution as a result of transaxonal transport of virus from trigeminal or cervical afferent fibers that innervate vessels. Ophthalmic zoster (HZO) might cause ophthalmoplegic syndromes, with secondary optic neuritis. Mechanisms include local orbital muscle inflammation and, viral spread from the ophthalmic branch of the fifth nerve with associated vasculopathy. A 72-year-old man developed a vesicular rash in the territory of C5-T5-6. Within four weeks, the patient developed headache, dysphagia, left facial and extremity ataxic weakness. Magnetic resonance imaging (MRI) revealed a right pontine infarction. A 66-year-old woman presented with right-sided painfull HZO. One week later she developed complete external ophthalmoplegia and blurred vision. MRI showed ill-defined signal alteration in the retrobulbar tissue. Three weeks later, the patient was admitted because of dysarthria, deviated tongue, left-sided limb weakness, and tactile hypoesthesia. Spinal fluid contained 23 lymphocytes/mm3 and increased protein. The serum contained antibodies to VZV IgG and IgM in both cases. The patients received intravenously acyclovir with improvement. This report confirms unusual occurrence of ipsilateral brainstem stroke after VZV reactivation in immunocompetent subjects.

BACKGROUND Varicella zoster virus (VZV) is a common viral infection, with primary infection presenting as fevers and pruritic vesicular rash. After staying dormant in the dorsal root ganglia, reactivation can lead to secondary infection. Meningitis is a rare a complication of VZV infection. CASE REPORT We report a case of a 44-year-old woman with no past medical history, presenting with severe frontal headache without meningeal signs or fevers, found to have VZV meningitis. CSF analysis revealed hypoglycorrhachia and she was treated successfully with combination of intravenous acyclovir and oral valacyclovir. CONCLUSIONS VZV meningitis can present with subtle clinical signs and symptoms and should be considered as a possible etiology for headaches without identifiable cause.

This case describes an uncommon presentation of herpes zoster in an adolescent with viral meningitis and concomitant genital shingles. A 15-year-old immunocompetent girl with background of well-controlled Graves' disease presented with 3 days of fever, frontal headache, terminal neck stiffness and photophobia. This was preceded by 4 days of pain and itch over vaginal and anal region. She had one dose of varicella vaccination at 18 months old and developed mild primary varicella infection around 5 years of age. Varicella zoster virus DNA was detected both in cerebrospinal fluid and in vesicles over her right labial majora. While there is no international consensus on the recommended duration of treatment for zoster with neurological complications, she was treated with intravenous acyclovir for 10 days with good clinical response. Her fever, headache and neck stiffness resolved after 2 days and genital lesions resolved after 9 days of antiviral therapy.

Varicella zoster virus (VZV) has been increasingly linked with encephalitis and atypical presentations in immunosuppressed patients. We present a patient with history of immunosuppressant intake for polymyositis who initially presented with throbbing frontal headache that raised the suspicion of migraine. She did not respond to anti-migraine medication and later developed stimulus induced myoclonus. She then had significant neurological decline and eventually became encephalopathic. Her initial imaging of brain was unremarkable which warranted further investigations. She was then diagnosed to be VZV positive in the cerebrospinal fluid (CSF) sample that confirmed VZV encephalitis. She responded well to IV Acyclovir treatment and her neurological function improved significantly. In this case, there was delay in diagnosis of VZV in the setting of immunosuppression and non-specific clinical presentation. Therefore, we encourage to strongly consider early VZV diagnostic work up and treatment in immunocompromised patients who can present with non-specific symptoms without a typical cutaneous rash.
