Hemichorea-hemiballism by branch atheromatous disease with a unique cerebral blood flow abnormality

Hemichorea-hemiballism (HCHB) is a rare manifestation caused by hyperglycemia or stroke [1,2]. The predominantly affected sites are the basal ganglia and thalamus [3,4]. However, why HCHB appears in only a few cases remains unclear. We herein report a case involving a man with branch atheromatous disease (BAD) in the internal putamen with the development of a cerebral blood flow (CBF) abnormality beyond the ischemic lesion and resultant HCHB.
