Klebsiella pneumoniae is a rare, but important cause of community-acquired meningitis. We report a case of fulminant Klebsiella pneumoniae meningitis complicated with ventricultis and brain abscess. A 65-year-old man admitted because of headache. He had a history of bacterial meningitis 6-months ago. The findings of CSF profile and culture was compatible with Klebsiella pneumoniae meningitis. Rapid progression of ventriculitis was found in a few days. Even though the ventriculitis improved, brain abscess developed in 25 days later.
