Abstract

We report a 16-year-old girl with Sydenham's chorea. Choreiform movements involved both sides of her body. MRI 2 months after the onset revealed abnormal increased signal on T2-weighted images and enlargement of the caudate and putamen bilaterally. MRI 5 months later showed resolution of the swelling, but with increased signal on T1-weighted images in the putamen, globus pallidus and the head of the caudate nucleus bilaterally, with slightly increased signal intensity on T2-weighted images.

摘要

我们报告一名患有 Sydenham 舞蹈病的 16 岁女孩。舞蹈样动作累及她身体的双侧。发病 2 个月后的 MRI 显示 T2 加权图像上信号异常增高，双侧尾状核和壳核增大。5 个月后的 MRI 显示肿胀消退，但双侧壳核、苍白球和尾状核头部在 T1 加权图像上信号增高，T2 加权图像上信号强度略有增加。
