Magnetic resonance imaging and single-photon emission computed tomography changes in hypoglycemia-induced chorea

We present two case studies, one of generalized chorea and one of hemichorea, both after severe hypoglycemia episodes. Both cases showed hyperperfusion in their SPECT scans. The MRI and SPECT findings serve as clues regarding the role of basal ganglion dysfunction associated with chorea. © 2003 Movement Disorder Society
