There is enlargement and increased T2 and FLAIR signal of the left medial temporal lobe. Increased T2 and FLAIR signal of the left insular cortex and temporoparietal cortex. Another lesion with similar abnormal signal is noted at the left thalamus. Also similar linear abnormal signal at the left side of the splenium of corpus callosum.
No significant peri-lesional oedema, however, there are mild mass effects in the form of effacement of the related cortical sulci, mild compression of the third ventricle and slight encroachment on the left aspect of circum-mesencephalic cistern.
No evidence of diffusion restriction.
Intermediate TE MRS revealed reduction in NAA and marked elevation of Cho and Cr peaks.
The above lesions did not show significant enhancement after contrast administration.
