MRI sagittal STIR images (A) of the cervical spine reveal ill-defined long segment hyperintensity with prominent cord expansion C2-C4 (red arrow); B shows axial cut with cord signal alteration at C3 (red arrow), and C post-contrast sagittal image showed no abnormal enhancement. MRI orbit Axial T1-weighted fat suppression post-contrast (D) and coronal images (E) reveals abnormal enhancement of left optic nerve pre-chiasmatic (intracanicular); (yellow arrow) with corresponding hyperintense on axial T2 weighted images (F) (yellow arrow) with no abnormality of the right optic nerve (blue arrow)

Fig1
T2 hyperintensity from C2-C4 without post-contrast enhancement. These results were suggestive of longitudinally extensive transverse myelitis and post-infectious transverse myelitis (Fig. 1). Brain and orbital MRI w/wo contrast revealed pre-chiasmatic (intracanicular) enhancement of the left optic nerve, suggestive of optic neuritis (Fig. 1).
