Postneurosurgical bacterial meningitis (PNBM) is an emergency and requires early diagnosis and treatment with appropriate antibiotics. The cornerstone of diagnosis is microbiological analysis of the cerebrospinal fluid (CSF) cytochemical characteristics such as leucocyte count, CSF glucose, and protein concentration and CSF: Serum glucose ratio. However, this is often misleading in PNBM. The role of CSF lactate assay for diagnosis and prognosis has been debated. This case report looks into the serial measurement of CSF lactates in PNBM. It also looks into the role of intrathecal colistin. CSF lactate showed a steady decrease corresponding to improvement in clinical condition. Hence, CSF lactate could have a better prognostic value than other conventional markers in PNBM. Intrathecal colistin, in conjunction with the standard antibiotics, can contribute to a quick resolution of the condition.
