Abstract

Hypoglycemic hemiplegia is an under-recognized manifestation of hypoglycemia and mimics cerebrovascular dis-ease, especially in elderly patients. We report a 70-year-old diabetic woman with hypoglycemic hemiplegia, whose dif-fusion-and perfusion- weighted images showed large cortical high signal intensities and hypoperfusion of the right hemisphere during the period of hypoglycemia. We suggest that the regional cerebral blood redistribution and selective vulnerability in hypoglycemia are responsible for the laterality of neurological deficits observed during hypoglycemic episodes Key Words : Hypoglycemia, Hemiplegia, Magnetic resonance imaging
