Spinal cord MRI. a Sagittal T2-weighted imaging showed long segmental hyperintensities from C2 to C6 of the spinal cord. b Inverted “V-sign” hyperintensity on axial T2-weighted imaging within the dorsal cervical spinal cord. c After 3 months of continuous immune therapy, there was a decreased signal on axial T2-weighted imaging, both horizontally and longitudinally. d After 3 months of continuous immune therapy, the inverted “V-sign” hyperintensity faded on axial T2-weighted imaging
