A case of hemichorea in a patient with poorly controlled diabetes is reported. T1-weighted magnetic resonance imaging (MRI) showed an unusual homogeneous high-intensity area in the corpus striatum. Of interest in the case was the fact that the globus pallidus, which was enhanced with gadolinium at the onset of hemichorea, showed homogeneous high-intensity on a subsequent T1-weighted image. This indicated that blood brain barrier destruction preceded the signal intensity change in the basal ganglia. As far as the authors could determine, this is the first reported case showing such enhancement during the course of diabetic hemichorea.
报告了1例糖尿病控制不佳患者出现偏侧舞蹈症的病例。T1加权磁共振成像（MRI）显示纹状体内有一个异常的均匀高强度区域。该病例有趣的是，在偏侧舞蹈症发作时钆增强的苍白球在随后的T1加权图像上显示为均匀高强度。这表明血脑屏障破坏先于基底节信号强度改变。据作者所知，这是首例报道的在糖尿病性偏侧舞蹈症病程中出现这种强化的病例。
