Abstract

Fluid-attenuated inversion recovery (FLAIR) MRI has become a cornerstone in the evaluation of infectious leptomeningitis. Its diagnostic utility stems from two distinct pathophysiological mechanisms: the failure of CSF signal suppression on unenhanced scans and T1-shortening effects following contrast administration. This case presentation compares these mechanisms to optimize the early detection of meningeal pathology.
