Sagittal T2-weighted image (a), transverse T2-weighted image (b), transverse FLAIR image (c), and diffusion-weighted image (d) showing a high-intensity signal in the splenium of the corpus callosum. Transverse apparent diffusion coefficient image (e) showing a low-intensity signal in the splenium of the corpus callosum. Contrast transverse T1-weighted image showing only some slight contrast enhancement of the leptomeninges (f)

SCC that was markedly hyperintense on diffusion-weighted images (DWI), fluid-attenuated inversion recovery (FLAIR) images, and T2-weighted images (T2WI); hypointense on the apparent diffusion coefficient (ADC) and slightly hypointense on T1-weighted images (T1WI) (Figure 1). Some increase was observed only in the enhancement of the leptomeninges (Figure 1A).
Non-contrast T2-weighted image showing a diffuse high-signal intensity inside the cervical and thoracic spinal cord (a). Contrast sagittal T1-weighted image showing diffuse meningeal enhancement over the conus medullaris (b). The parenchyma was enhanced heterogeneously on the contrast T1-weighted image (c)

T2WI showed diffuse high-signal intensity inside the cervical and thoracic spinal cord (Figure 2A). The pia mater over the cervical spinal cord, the thoracic spinal cord, and the parenchyma were enhanced heterogeneously, whereas diffuse meningeal enhancement was present over the conus medullaris (Figure 2B, 2C).

On follow-up five weeks after the initial examination, gait ataxia and cranial and spinal MRI findings had resolved (Figures 3 and 4); at seven weeks, the urodynamic study was normal.
Non-contrast T2-weighted image of the cervical and thoracic spinal cord (a), contrast sagittal T1-weighted image of the conus medullaris (b), and contrast T1-weighted image of the cervical and thoracic spinal cord (c) reveal normal findings
