Abstract
A case of hemichorea in a patient with poorly controlled diabetes is reported. T1-weighted
magnetic resonance imaging (MRI) showed an unusual homogeneous high-intensity area
in the corpus striatum. Of interest in the case was the fact that the globus pallidus,
which was enhanced with gadolinium at the onset of hemichorea, showed homogeneous
high-intensity on a subsequent T1-weighted image. This indicated that blood brain
barrier destruction preceded the signal intensity change in the basal ganglia. As
far as the authors could determine, this is the first reported case showing such enhancement
during the course of diabetic hemichorea.
