Cerebral Vasculitis in a Case of Meningitis.

Cerebral vasculitis is a serious complication of meningitis with Streptococcus pneumoniae. We report a 5 yr old girl who was admitted in May 2015 at Fortis Hospital, Kolkata, India and was diagnosed to have pneumococcal meningitis with vasculitis on DWMRI within a week of onset of fever. She was given high dose of methyl-prednisolone simultaneously with antibiotics and successfully treated without any neuro-sequelae. Although vasculitis has been documented to develop as sequelae to bacterial meningitis usually in the second week, our patient had an early presentation. Treatment with high dose steroid along with antibiotics resulted in dramatic improvement with no neurodeficit. DW-MRI is an important investigation to pick up early, evidence of vasculitis in a patient with meningitis who is showing neurological deteriorations despite improvement in blood parameters.
