Gardnerella vaginalis purulent meningitis in an adolescent male: a case report
Abstract
Abstract Background We report a rare case of Gardnerella vaginalis found in the cerebrospinal fluid of a young boy. Case presentation A 14-year-old boy was admitted to hospital with headache, vomiting, fever, drowsiness and positive meningeal irritation signs on examination. Cerebrospinal fluid (CSF) shows white blood cell and protein were elevated, and glucose was low. Traditional aerobic and anaerobic culture of CSF did not grow any organisms. However, metagenomic next-generation sequencing (mNGS) reveals G. vaginalis in his CSF. The patient was diagnosed with purulent meningitis, and treated with intravenous meropenem and linezolid for a week, followed by oral administration of amoxicillin for two weeks. He recovered without sequelae. Conclusions Purulent meningitis caused by Gardnerella vaginalis is extremely rare. Metagenomic next-generation sequencing of CSF should be highlighted for early diagnosis. With effective antibiotic treatment, the prognosis was excellent.
