Generalized chorea induced by an unilateral anterior cerebral artery territorial infarction

Abstract

Generalized chorea caused by unilateral cerebral infarction has rarely been reported. A 58-year-old woman presented involuntary movement in her all extremities after acute cerebral infarction on her right anterior cerebral artery territory. The involuntary movements were diagnosed as generalized chorea. We didn't find any cause of generalized chorea except the acute cerebral infarction. Here, we described the case of generalized chorea after unilateral cerebral infarction discussing the possible mechanisms.

Magnetic resonance images at the level of right cingulate gyrus (A1–A4) and corpus callosum (B1–B4). The lesions had high signal intensities on diffusion weighted images (A1, B1) and low signal intensities on apparent diffusion coefficient map (A2, B2). T2-weighted images showed high signal intensity on right cingulate gyrus, corpus callosum, and left caudate nucleus (A3, B3). T1-weighted images showed low signal intensity lesion on left caudate nucleus (B4) and isosignal or subtle low signal intensities on the right cingulate gyrus (A4) and corpus callosum (B4).
