Axial diffusion-weighted (a), ADC maps (b) and T2-weighted (c) images at the level of the pons (left images) and basal ganglia (right images) obtained in a 54-year-old man who developed impaired consciousness after rapid correction of severe hyponatraemia. Diffusion-weighted and T2-weighted images revealed white matter hyperintensities that were more evident in the middle cerebellar peduncles (arrows) and in the cortico-spinal tract (arrowheads) consistent with osmotic extrapontine myelinolysis. ADC values were mildly decreased
