FIG 2. Case 2. Postcontrast axial T1-weighted image (A) (500/20/1) shows subtle enhancement with surrounding hypointensity within the genu of the corpus callosum (arrows). FLAIR images (B, C) (8900/140/1) show abnormal increased signal within both sides of the genu and body of the corpus callosum. Axial FLAIR images (D, E) (8900/140/1) from follow-up MR imaging performed 3 weeks later showed almost complete resolution of the abnormal signal within the corpus callosum
