Axial T2W and FLAIR images show a hyperintense lesion in the precentral gyrus, with
surrounding vasogenic edema that also extends to the postcentral gyrus.
Left: Coronal T1WI demonstrates the center of the lesion to be more hypointense than the
Middle & Right: Post contrast Coronal and Axial T1WIs reveal thick ring enhancement.
Single voxel short TE spectroscopy over the lesion show elevated choline, lipid and lactate
peaks. Spectroscopy over the normal brain shows a normal spectrum.
