Abstract
Sphingomonas paucimobilis is an aerobic gram-negative bacillus. The bacteria can cause infections, which can be devastating and, therefore, the patients need adequate and early antibiotic cover. We are presenting an interesting case of meningitis secondary to an unusual S. paucimobilis infection. This is the second case to our knowledge in the literature on meningitis due to S. paucimobilis. The 31-year-old previously healthy man presented with 2 months' history of weight loss and loss of appetite. He had fever and headache for 3 weeks. He was also speaking irrelevantly for 3 weeks. He had change of behaviour for 1 day. The patient was a farmer and worked in the soil. On examination, he was not responding to questions and was not obeying commands. Computed tomography (CT) brain with contrast revealed meningeal enhancement and cerebral oedema. Lumbar puncture was performed. Cerebrospinal fluid (CSF) opening pressure was more than 50 cm H2O. CSF analysis showed meningitis picture with raised white cell count of 210/μL (predominantly neutrophils), glucose 3.1 mmol/L, and raised protein 2.47 g/L. He was given intravenous ceftriaxone. The following day, his condition deteriorated. CSF culture grew S. paucimobilis sensitive to ceftriaxone. S. paucimobilis causes severe meningitis. This can lead to hydrocephalus, which results in a need for extraventricular drainage. A good occupational history is important with regard to finding the aetiology of serious meningitis (including rare bacteria) even before the culture result is known. Appropriate treatment can be given early and adequately to prevent mortality.
