  Fig. 1. (A) Sagittal T2-weighted and (B) axial T2-weighted magnetic resonance images show focal swelling, with the enhanced signal intensity of the central grey matter of the conus medullaris (red arrows). (C, D) Signal hyperintensity of the conus medullaris (blue arrow) is found on apparent diffusion coefficient mapping, with no significant restricted diffusion on diffusion-weighted imaging.
