Overview

CT scan may help identify the patients with bacterial meningitis who are at increased risk of cerebral herniation with lumbar puncture. Routine screening with CT scan may be indicated in such patients before undergoing lumbar puncture. Ct scan may also help to identify the complications of bacterial meningitis such as epidural empyema, subdural empyema, ventriculitis and cerebral abscess.

CT scan

Routine screening with CT scan may not be indicated in all patients with bacterial meningitis. However, it may be indicated in patients with suspected case of bacterial meningitis to exclude mass lesions and increased intracranial pressure before a lumbar puncture to prevent cerebral herniation. According to Infectious disease society of America guidelines 2004, the presence of following risk factors may necessitate the CT scan before undergoing lumbar puncture:

  • Papilledema
  • Sudden onset seizures
  • Known history of mass lesion or stroke
  • Immunosuppression(HIV, organ transplant, steroid therapy )
  • Focal neurological deficit
  • Altered level of consciousness

CT scan findings which may help diagnose patients with bacterial meningitis and its complications may include the following:[1]
