Figure 2: Coronal T2FS (top row left), coronal T1 post-contrast fat-saturated (FS) (top row right), and axial T1 post-contrast FS images (middle row left) through the orbits demonstrate a short segment T2 hyperintense lesion with associated enhancement in the left optic nerve. Sagittal STIR (middle row right), sagittal T1 post-contrast FS (bottom row left), and axial T2 images (bottom row right) of the cervical spine demonstrate an enhancing, short segment (<2 vertebral bodies in length), T2/STIR hyperintense lesion in the peripheral aspect of the spinal cord. The differential diagnosis includes both Multiple Sclerosis and Neuromyelitis Optica. However, the length of the lesion in both the spinal cord and optic nerve favor multiple sclerosis. The patient's CSF demonstrated oligoclonal bands.
