Figure 7 (A-D): Tumefactive demyelination. A 5-year-old male came with history of recurrent episodes of muscle weakness and seizures. Multiple round to oval lesions are seen in the left parietal and frontal lobes (arrows in A), genu (arrow in B), and body of corpus callosum. They are peripherally hypointense and centrally hyperintense on T2-weighted image (A) and show suppression on FLAIR (B) image. Their margins show partial ring enhancement on post-contrast T1-weighted image (arrow in D) and partial peripheral restricted diffusion on diffusion-weighted image (arrow in C), suggestive of active margins of demyelinating plaques
