Original Paper


Movement disorders are a recognized complication of stroke. Here we present a case of hemichorea-hemiballism (HCHB) after stroke. Basal ganglia and thalamus are typically recognized as sites responsible for HCHB. The MRI scan showed acute infarction which was unexpectedly present in both sides of corona radiate and cortex, but not in basal ganglia. This cortical HCHB could have evolved due to hypoperfusion of basal ganglia undetectable at the MRI scan or due to interruption of excitatory connections from the cerebral cortex to basal ganglia.
