The authors report a case of severe hypoglycemic encephalopathy in an elderly patient. The magnetic resonance images showed bilateral cortical signal changes and basal ganglia lesions, which spared the thalami. The lesions were bright on fluid‐attenuated inversion recovery and diffusion‐weighted images and dark on the apparent diffusion coefficient map, being more conspicuous on the diffusion‐weighted images than on the fluid‐attenuated inversion recovery images. A literature review of the imaging features and pathophysiological mechanism in comparison with those of hypoxic ischemic injury is discussed.
