Brain MRI. Apparent diffusion coefficient (ADC) and T2 images showed altered signal in the left basal ganglia extending to the left thalamus, midbrain and pons with the lesion causing mild fullness of the ipsilateral lateral ventricle due to compression of the left foramen of Monro
用20号无菌针头在前臂屈面中部斜行刺入 约0.5 cm沿纵向稍作捻转后退出,24-48h后局 部出现直径>2 mm的毛囊炎样小红点或脓疱疹 样改变为阳性。此试验特异性较高且与疾病活 动性相关,阳性率约60-78%。静脉穿刺或皮 肤创伤后出现的类似皮损具有同等价值。

Brain MRI shows lesions in the pons extending to bilateral middle cerebellar peduncles, which are hypointense on T1weighted imaging (A), hyperintense on T2-weighted imaging (B), with heterogeneous contrast enhancement (C).
