(a and b) Diffusion-weighted image showing central pontine hyperintensity. Corresponding area on ADC mapping shows hypointensity, suggesting a diffusion restriction in the central pons. (c) Sagittal T2-weighted image showing a hyperintensity in the central pons. (d) Axial T2-weighted image showing a triangular area of hyperintensity in the central pons. The arrow represents the proposed site of VI nerve fascicle injury

T2 hyper-intensity which also showed evidence of restricted diffusion [Figure 1a and b] consistent with central pontine myelinolysis (CPM). The MRI of orbits, MR angiogram and MR venogram were unremarkable.
