After CSF analysis, clinicians favoured the diagnosis of viral meningitis and the patient received empirical antiviral therapy. 2Two weeks followup was negative for leptomeningeal enhancement.
The sensitivity of contrast enhanced FLAIR sequences is remarkably higher in comparison to contrast enhanced T1-weighted sequences for the imaging diagnosis of meningitis. The main reason is the better distinction between enhancing meninges and enhancing cortical veins. The signal of contrast enhanced cortical veins is attenuated only on FLAIR images.1
