  		Fig 1. A and B, Axial FLAIR (A) and postgadolinium T1-weighted (B) images show a ring-enhancing tumefactive lesion with edema and mass effect. C and D, Axial FLAIR (C) and postgadolinium T1-weighted (D) images 1 month after treatment. The pattern of contrast enhancement thicker medially suggests demyelination. The lesion does not show restricted diffusion on diffusion-weighted images and is hyperintense on the apparent diffusion coefficient images.
