  • Aux modality: T1 C+

The lesion is hypointense on T1WI, mildly hyperintense on T2WI, with dual rim best seen on T2WI. No calcifications or blood products within the lesion on T2GRE images. Diffusion-weighted images (DWI) shows hypointensity and no restriction. The lesion shows ring enhancement after IV contrast administration. MR-spectroscopy shows a mild amino-acid peak (0.9 ppm) and severe elevation of the lipid/lactate peak (1.33 ppm). There is also marked depression of the NAA (2.03 ppm) and Creatine (3.02 ppm), no depression of the choline. Brain MR and MRS findings are most keeping with cerebral toxoplasmosis and less likely brain abscess.
