Aseptic meningitis


The CSF culture revealed no growth of microorganisms. The case was handled as aseptic meningitis, which basically corresponds to an inflammation of the brain meninges not caused by pus-producing bacteria. Causes of this type of meningitis are viruses and non-infectious conditions such as systemic lupus erythematosus, lymphoma, leukemia, and NSAIDs and other drugs. 

Enteroviruses infection is considered the main cause, particularly during summer and autumn 1

It is important to note how the addition of a post-contrast FLAIR sequence helped in spotting the meningeal enhancement. MRI protocols for brain infection or leptomeningeal diseases can be benefited from this acquisition.
