Figure 1: (a) shows hypointense lesions in left fronto-parietal and right parietal lobes on T1W image. (b) On FLAIR axial image centre shows suppression of signal. Perilesional vasogenic edema seen. (c) Characteristic 'broken ring' of contrast enhancement seen. (d) Follow-up FLAIR image after treatment with steroids shows decrease in size of the lesionsSecond case (e) T1W and (f) FLAIR axial images showing a hypointense lesion in the right peritrigonal white matter with surrounding vasogenic edema, (g) Peripheral contrast enhancement and (h) Hypoperfusion on Dynamic T2* perfusion rCBV map
