T2w sagittal images of the cervical and thoracic spine (a,b) along with axial images (c,d) reveal diffuse long segmental T2w hyper-intense signal in the spinal cord more in the central gray matter region along with mild cervical cord swelling.

Whole spine contrast MRI showed a mild diffuse increase in cord bulk with an intramedullary hyperintense signal on T2 weight images involving the entire length of the spinal cord and conus medullaris, indicating a longitudinally extensive transverse myelitis (Figure 1).
Flair contrast image of the brain (a) and T1w contrast (b,c) image of the cervical and thoracic spine shows mild smooth enhancement along the pial surface of spinal cord.
