Answer

Finally, neuroimaging studies are helpful in the detection of CNS complications of bacterial meningitis, such as the following (see the images below):

  • Hydrocephalus

  • Cerebral infarct

  • Brain abscess

  • Subdural empyema

  • Venous sinus thrombosis

    Chronic mastoiditis and epidural empyema in a pati Chronic mastoiditis and epidural empyema in a patient with bacterial meningitis. This axial computed tomography scan shows sclerosis of the temporal bone (chronic mastoiditis), an adjacent epidural empyema with marked dural enhancement (arrow), and the absence of left mastoid air.
    Subdural empyema and arterial infarct in a patient Subdural empyema and arterial infarct in a patient with bacterial meningitis. This contrast-enhanced axial computed tomography scan shows left-sided parenchymal hypoattenuation in the middle cerebral artery territory, with marked herniation and a prominent subdural empyema.
