Figure 1: MRI scan showing T2-weighted and corresponding diffusion-weighted images. The images in the upper row (a-d) represent the initial MRI scan done at the time of presentation of symptoms of osmotic demyelination syndrome, which was unremarkable. Follow-up MRI (e-h) done 2 weeks after the initial MRI scan shows subtle hyperintensity in the basal ganglia, thalamus, and pons with restricted diffusion in the pons, consistent with the diagnosis of osmotic demyelination syndrome
