Overview
The diagnosis of fungal meningitis mainly relies on the results of the cerebrospinal fluid (CSF) analysis, stain and culture. The role of imaging is to rule out other differential diagnosis of the initial presentation. In addition, brain imaging must be done when the patient has signs of increased intracranial pressure to prevent brain herniation.
CT scan
- CT studies of the brain and spinal cord may help in ruling out other medical conditions that might have a similar presentation to fungal meningitis.
- CT scan is done to rule out tumors or para-meningeal infections (brain abscess)
- CT scan must be done prior to a lumbar puncture in patients with signs of increased intracranial pressure in order to prevent brain herniation.[1]
