Axial FLAIR image (a) at the orbit level shows normal signal of both optic nerves. Sagittal T2WI (b) of cervical spine shows normal cord signal.

Contrast enhanced magnetic resonance imaging (MRI) of the brain and spine were done to look for any demyelinating lesions in central neuroaxis which was unremarkable (Figure 1).

MRI of dorsal spine sagittal (a), coronal (b), and axial (c). T2WI shows focal cord expansion at the conus with increased cord signal intensity predominantly at the center.

MRI of the spine showed swelling of spinal cord at conus level with increased T2 signal and patchy contrast enhancement (Figure 2), the rest of spinal cord and brain was normal.

Axial T2WI brain MRI (a) shows multiple hyperintense lesions in pons and middle cerebellar peduncle. Post contrast coronal T1WI (b) shows patchy and curvilinear enhancement mimicking CLIPPERS. Follow up MRI: Axial T2WI (c) and post contrast T1WI (d) shows reduced size and number of the lesions and no enhancement.

A repeat MRI of the brain showed significant decrease in lesion size and enhancement (Figure 3).
