Central Pontine Myelinolysis with Minimal Hyponatremia in the Setting of AIDS

Figure 1

Brain magnetic resonance imaging shows a lesion in the central pons with imaging characteristics consistent with demyelination. The lesion is hyperintense on both (a) Fluid-Attenuated Inversion Recovery Image and (b) Diffusion-Weighted Imaging. The lesion is hypointense on (c) T1-weighted sequence.
