目的：探讨脑损伤后锥体束华勒氏变性的MRI 表现，以提高其诊断的准确性。方法收集25例原发性脑损伤后锥体束华勒氏变性的 MRI 资料，并分析其影像特征。结果25例患者中，原发病灶均位于幕上，2例于原发病灶同侧锥体束走行区出现连续的条带样长 T1或等 T1，长 T2改变，FLAIR 及 DWI 呈高信号。2例 T1 WI 呈低信号，T2 WI 及 FLAIR 呈高信号，DWI 等信号。21例为 T1 WI 低信号，T2 WI 高信号， FLAIR 高信号，DWI 等低信号且合并脑干萎缩。结论MRI 是诊断脑损伤后锥体束华勒氏变性的可靠方法。

Objective To analyze the MRI findings of Wallerian degeneration in pyramidal tract after cere-bral injury for improving the diagnosis accuracy.Methods The MRI findings of Wallerian degeneration in pyramidal tract in 25 cases were analyzed in association with the primary cerebral injury.Results All the primary diseases were above the tentorium of cerebellum in 25 cases,MRI in 2 cases demonstrated a continuous thin band -like long T1 or isometric T1 and long T2 abnormal changes in pyramidal tract,hyperintensify on FLAIR and DWI.2 cases showed hypointensify on T1 WI,hyperintensify on T2 WI and FLAIR,isointensity on DWI.21 cases showed hypointensify on T1 WI,hyperintensify on T2 WI and FLAIR,isointensity or hypointensify on DWI with brainstem atrophy.Conclusion MRI is valuable in the diagnosis of Wallerian degeneration in pyramidal tract after cerebral injury.
