PG - e4636 LID - 10.7759/cureus.4636 [doi] LID - e4636 AB - We present a case of a 32-year-old woman with signs and symptoms of idiopathic intracranial hypertension (IIH), but who, upon further investigation, was found to have human herpesvirus-6 (HHV-6) in both cerebrospinal fluid (CSF) and serum. This rare cause of meningitis in an immunocompetent individual and a relatively unique presentation is described along with a review of proper diagnostic workup and treatment. HHV-6 meningitis is commonly detected via molecular diagnostics and thus needs confirmatory testing of viral load of acellular compartments or viral serology. The reason for this added diagnostic step is due to the incorporation of the virus into the host DNA, leading to increased false-positive results on screening tests. In this case, proper diagnosis, treatment, and follow-up were pursued by following guidelines proposed in the literature of HHV-6 meningitis.
