A Rare Case of Meningitis in the Absence of Cerebrospinal Fluid Pleocytosis

Sphingomonas paucimobilis is a nonfermentative gram-negative bacillus of low pathogenicity. The organism has been involved in causing a wide range of infections in community and hospital settings. Only 3 cases of meningitis caused by this organism have been reported so far. We report a rare case of S paucimobilis meningitis who presented with atypical symptoms. A 50-year-old female presented with headache, dizziness, chills, shakiness, and neck pain along with nuchal rigidity. On physical examination, severe neck rigidity along with decreased range of motion was noticed. Her cerebrospinal fluid showed gram-negative rods, and she was started on meropenem. The cerebrospinal fluid grew S paucimobilis sensitive to meropenem. She subsequently showed significant improvement and was discharged home on intravenous meropenem for 21 days and showed complete recovering in 5 weeks.
