Abstract
- There have been few reports of hypoglycemic encephalopathy (HE) with unilateral brain lesion. A 66-year-old male with hypoglycemia, who had history of diabetes and recent poor oral intake, presented with amnesia and confusion. Diffusionweighted imaging (DWI) showed high signal intensity in left hippocampus, which was low on apparent diffusion coefficient (ADC) map. By intravenous glucose, the symptoms improved besides amnesia for hypoglycemic period. Follow-up DWI revealed no lesion and single photon emission computed tomography (SPECT) showed decreased perfusion in left temporo-parieto-frontal area. We experienced a case of HE with a reversible unilateral hippocampal lesion.
