Group B streptococcal (GBS) meningitis is uncommon in non-puerperal adults outside of significant immunocompromise or structural abnormalities. We describe a relatively healthy 62-year-old man with GBS bacteremia, abnormal lumbar puncture, and MRI-confirmed leptomeningitis, ventriculitis, right cerebellitis, and cerebritis who presented without overt symptoms of meningitis. The suspected source of infection was a high-inoculum genitourinary infection in the setting of hydronephrosis and recent cystoscopy. We performed a literature review of previous cases and clusters of GBS meningitis. With increasing recognition of invasive GBS infection among adult patients, and in light of our patient’s atypical presentation, we propose that an index of suspicion for GBS meningitis be maintained, even for patients who would traditionally have been considered at lower risk.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
