Movement disorders associated with cerebral cavernous malformations (CM) are seldom reported, and chorea, in particular, is rarely associated with a CM located in the caudate nucleus. Here we report a 78-year-old female patient with chorea, who presented with choreiform movements due to a CM in the contralateral caudate nucleus. A brain MRI was obtained and compared with that obtained before the onset of chorea. The new images did not reveal further extralesional hemorrhage from the CM when compared with the previous images. The choreiform movements showed spontaneous improvement and then disappeared completely. We reviewed previous reports of patients with chorea associated with a CM, and conclude that CM located in the caudate nucleus can cause chorea.
与脑海绵状血管畸形（CM）相关的运动障碍很少见报道，特别是舞蹈症与位于尾状核的 CM 相关的情况很少见。在此，我们报告了一例 78 岁女性舞蹈症患者，因对侧尾状核的 CM 而出现舞蹈样运动。进行了脑部 MRI 检查，并与舞蹈症发作前的 MRI 进行了比较。与之前的图像相比，新图像未显示 CM 进一步发生病灶外出血。舞蹈样运动自发改善，然后完全消失。我们回顾了之前报道的与 CM 相关的舞蹈症患者，得出结论，位于尾状核的 CM 可引起舞蹈症。
