Answer

Imaging for suspected viral meningitis and encephalitis may include CT scanning of the head, with and without contrast, or MRI of the brain, with gadolinium.

CT scanning with contrast helps to rule out intracranial pathology. Contrasted scans should be obtained to evaluate for any enhancement along the meninges and to exclude cerebritis, intracranial abscess, subdural empyema, and other lesions.
