Hemichorea may point to a structural lesion in the contralateral basal ganglia with a large list of possible causes. Cavernous angioma may be rarely a possible cause for acute appearance of this movement disorder.
We present a rare case of a 32-year-old female patient with hemichorea caused by a cavernoma (or cavernous angioma) in the contralateral insula and putamen with complete improvement of symptoms with surgical resection of the lesion.
We believe that surgical resection of basal ganglia cavernomas may be feasible with minor risks and resolution of clinical symptoms in the immediate postoperative period.
偏侧舞蹈症可能提示对侧基底节区存在结构性病变，其可能病因很多。海绵状血管畸形可能很少见，但也可能是引起这种运动障碍急性发作的原因。
我们报告了一例罕见病例，一名 32 岁女性患者因对侧岛叶和壳核海绵状血管畸形引起偏侧舞蹈症，手术切除病变后症状完全改善。
我们认为，基底节海绵状血管畸形的手术切除可行，风险较小，术后即刻可缓解临床症状。
