[Hypoglycemia].

Hypoglycemia may lead to acute hemiplegia. The most common diffusion-weighted MRI finding in patients with hypoglycemic hemiplegia is a hyperintense internal capsule lesion, which mimics acute ischemic stroke. In addition to the internal capsule lesion, various MRI findings have been reported in patients with hypoglycemia(including hyperintense lesions in the cerebral cortex, basal ganglia, subcortical white matter, and splenium of the corpus callosum). It has recently been reported that hypoglycemic brain damage starts in the large white matter tracts, such as the internal capsule, and spreads to the entire brain, including the gray matter. However, the mechanism underlying the development of focal signs, such as hemiplegia in metabolic disorders, which affects the entire brain, remains unclear.
