A Coronal T2-weighted MRI displays hyperintense signal along the corticospinal tracts bilaterally (“wine glass” sign). B On axial fluid attenuated inversion recovery (FLAIR), a hyperintense lesion is shown in the left middle cerebellar peduncle (green arrow). On brain MRI, no contrast enhancing lesions or lesions with diffusion restriction were depicted, while the optic nerves had normal appearance (images not shown). C Sagittal T2-weighted spine MRI shows longitudinally extensive thoracolumbar spinal cord lesions, with combined gray/white-matter involvement, affecting more than two-thirds of the thoracic spinal cord’s cross-sectional area on axial T2-weighted MRI sequence (D), findings compatible with transverse myelitis. E Sagittal T1-weighted gadolinium-enhanced MRI reveals contrast-enhancing lesions in the cervical and thoracic spinal cord (purple and orange arrows, respectively)
