Legend Axial T2W and FLAIR images show a hyperintense lesion in the precentral gyrus, with surrounding vasogenic edema that also extends to the postcentral gyrus.

Legend Left: Coronal T1WI demonstrates the center of the lesion to be more hypointense than the surrounding edema. Middle & Right: Post contrast Coronal and Axial T1WIs reveal thick ring enhancement.

Legend Single voxel short TE spectroscopy over the lesion show elevated choline, lipid and lactate peaks. Spectroscopy over the normal brain shows a normal spectrum. Key words: mri mrs white matter disease demyelinating

Brain Diagnosis: Tumefactive MS
