case_images: A 27-year-old woman with an unremarkable previous medical history presented with altered mental status after two days of fever and headache ( Figure 1 ).
case_images: (A, B) MRI of the brain on day 3. A single, ovoid-shaped lesion is seen in the splenium of the corpus callosum with increased signal on diffusion-weighted imaging (A) and fluid inversion recovery sequences (B). (C, D) MRI of the brain on day 22 shows full remission of the lesion in the splenium corpus callosum.

case_images: MRI of the brain, performed on day one and day three, revealed a single, ovoid-shaped lesion in the center of the SCC with a hyperintense signal on both T2-weighted imaging and DWI as well as low ADC map values ( Figures 2A, B ). Brain MRI on day 22 showed complete resolution of the SCC lesion and did not detect any new lesions ( Figures 2C, D ).
case_images: MRI of brain and cervical spine, MS presentation. New T2-hyperintense lesions are seen, amongst others, in the right paramedian medulla oblongata (A), in the right inferior cerebellar peduncle (C), in the periventricular white matter (D) and in the cervical spinal cord (E). Contrast enhancement is seen, amongst others, with the lesion in the right paramedian medulla oblongata (B).

case_images: MRI revealed a T2-hyperintense, round-shaped, contrast enhancing lesion in the right paramedian medulla oblongata ( Figures 3A, B ). Multiple other new T2-hyperintense lesions located in the body of the corpus callosum, in the right superior cerebellar peduncle ( Figure 3C ), in the periventricular white matter ( Figure 3D ) and juxtacortical to the left gyrus rectus, were detected. In addition, two small, T2-hyperintense, non-enhancing lesions were identified in the cervical spinal cord ( Figure 3E ).
