Case Report: Group B Streptococcus meningitis in an adolescent  

Streptococcus agalactiae (group B Streptococcus, GBS) usually colonizes the gastrointestinal and lower genital tracts of asymptomatic hosts, yet the incidence of invasive disease is on the rise . We describe a case of an 18 year old woman, recently diagnosed with lupus, who reported a spontaneous abortion six weeks prior to her hospitalization. She presented with fever, altered mental status, and meningeal signs, paired with a positive blood culture for GBS. Magnetic resonance imaging of her brain demonstrated an extra-axial fluid collection, and she was diagnosed with meningitis. She received prolonged intravenous antibiotic therapy and aggressive treatment for lupus, leading to clinical recovery. This case illustrates the importance of recognizing GBS as a potential pathogen in all patients presenting with CNS infection .
