Atypical Presentation of Aseptic Meningitis Due to Varicella Zoster: A Case Report

INTRODUCTION: Varicella zoster virus (VZV) meningitis is primarily an infection of the immuno-compromised. However, it can also affect immunocompetent individuals. Reactivation of VZV typically presents with a distinct dermatomal rash suggestive of varicella zoster, but there have also been reports of VZV meningitis presenting without a rash. CASE REPORT: We describe a case of VZV meningitis in a healthy, 30-year-old male presenting to the emergency department shortly after receiving his first coronavirus disease 2019 vaccination. He was treated with intravenous acyclovir and then discharged home on oral valacyclovir. CONCLUSION: Emergency physicians should consider aseptic meningitis in immunocompetent patients presenting with atypical headaches in this population.
