Human herpesvirus 7 induced aseptic meningitis in an immunocompetent adult presenting with unusual neurological symptoms: a case report

We report a rare case of viral meningitis induced by HHV-7 in a 37-year-old immunocompetent female, whose initial symptoms were unusual, presenting primarily with lower limb pain and numbness. Laboratory tests revealed HHV-7 deoxyribonucleic acid (DNA) in the CSF, confirming the diagnosis of aseptic meningitis. This case emphasizes the importance of considering HHV-7 in the differential diagnosis of viral meningitis, even without classic systemic signs. Despite the absence of specific antiviral therapy for HHV-7, supportive care remains effective. This case adds to the growing evidence on HHV-7 as an under-recognized cause of aseptic meningitis, particularly in immunocompetent individuals.
