Axial FLAIR (A) and sagittal postcontrast T1-weighted MR (B) images demonstrate a heterogeneously enhancing right parietal mass, with surrounding vasogenic edema. MR spectroscopy (TE = 30 ms) (C) shows a decrease in the NAA (at 2.02 ppm) and creatine (Cr) (at 3.0 ppm) peaks and elevation of the choline (Cho) (at 3.2 ppm) and lactate (Lac) and/or lipid peaks (at 1.33 ppm).
