case_images: (A) Parasagittal T2-weighted image of the brain, showing diffuse T2-weighted hyperintensity within the brainstem (arrows). (B) Sagittal plane post-contrast T1-weighted image showing focus of contrast enhancement within the medulla (arrows). (C) Transverse plane T2-weighted image of the brain at the level of the interthalamic adhesion showing diffuse T2-weighted hyperintensity within the right parietal lobe (arrows). (D) Transverse post-contrast T1-weighted image at the level of the caudal cerebellar vermis showing small focus of contrast enhancement within the brainstem (arrow).

case_images: MRI of the brain revealed diffuse, patchy, multifocal, subtle hyperintensities on T2 weighted images within the medulla, the pons, the midbrain and thalamus (Figure 1A), as well as within the corona radiata of the right cerebral hemisphere in the region of the parietal lobe (Figure 1C). Mild multifocal contrast enhancement was noted within the internal capsule, corona radiata, the medial thalamic nuclei, the midbrain and the periphery of the pons and medulla (Figures 1B,D). Multiple dehydrated intervertebral disks throughout the thoracic and lumbar spinal cord but no significant compression was noted along the length of the spinal cord that was imaged.

case_images: A conscious concentric needle EMG examination of the periauricular muscles was performed with the animal immobile which revealed marked high amplitude spontaneous activity with frequent doublets (Figure 2).
