纹状体病变后黑质继发变性10例分析

Analysis of 10 cases with secondary nigral degeneration after striatal lesions

目的:探讨纹状体病变后黑质继发变性的临床特点及影像变化。方法:分析纹状体病变患者10例的颅脑磁共振资料。结果:纹状体病变后黑质继发变性在MRI上表现为在纹状体病变同侧的黑质异常信号,T1WI上信号减低或相等,T2WI上信号增高,在DWI、FLAIR上表现为高信号。结论:纹状体病变后可出现黑质继发变性,这种变性在MRI上有特征性表现。

Objective:To investigate the clinical features and imaging changes of secondary nigral degeneration after striatallesions.Methods:The magnetic resonance imaging data of 10 cases of patients with striatal lesions were analyzed.Results:The MRIof secondary nigral degeneration after striatal lesions showed nigra in the same side of striatal lesions had abnormal signal,withreduced or equal signal on T1WI and increased signal on T2WI,DWI and FLAIR showed high signal.Conclusion:Secondary nigraldegeneration could occur after striatal lesions and the degeneration had characteristic manifestations on MRI.
