MRI

• Brain MRI is helpful in the diagnosis of neoplastic meningitis.
• On MRI, neoplastic meningitis is characterized by:

MRI component	Findings
T1	Usually normal
T2	Usually normal
T1 with contrast	Leptomeningeal enhancement scattered over the brain in a 'sugar coated' manner (diagnostic)
Fluid-attenuated inversion recovery (FLAIR)	Abnormally elevated signal within sulci
