Cortical Hemiballismus Associated With an Insular and Temporal Lobe Infarct

A 61-year-old man presented with acute left arm weakness, left facial droop, and left homonymous hemianopia. He received intravenous thrombolysis and symptoms resolved. Two days later, he developed left hemichorea-hemiballismus that resolved spontaneously in less than 48 hours. Magnetic resonance imaging of the brain showed an acute infarct of the right insular and temporal cortex without subcortical involvement. This suggests that movement disorders may also arise from injury of cortical structures, specifically the insular and temporal cortex, as seen in this case report.
