case_images: The analysis of MRS findings was done using the standard software provided by the manufacturer. The MRI scan again confirmed the presence of extensive signal abnormality, which unchanged in size from the previous scan (Figure 1). The MRS (SV and CSI) through the abnormal areas was extensively assessed but showed no alteration in choline and N-acetyl aspartate (NAA) peaks compared to normal brain tissue and was entirely within normal limits (Figures 2 and 3).
case_images: MRS CSI spectra (grid-2A) showing no alteration in metabolite ratios between normal (Figure 2(b)) and abnormal signal area of the brain (Figure 2(c)).

case_images: Axial T2 (a), coronal FLAIR (b), and axial T1 post-Gadolinium image (c) from 6-months followup MR scan, showing significant progression of the lesion and a new area of enhancement in the left parietal lobe.

case_images: An area of enhancement in the left parietal lobe was also present, measuring 19 x 18 mm (Figure 4).
