摘 要: | 目的:探讨颅内病变继发锥体束Wallerian变性的磁共振表现,以提高对该继发改变的认识和诊断。方法:收集颅内病变继发锥体束Wallerian变性的患者23例,对原发病变及Wallerian变性的MRI表现进行分析。结果:所有原发病变均位于幕上,单侧发病22例,双侧发病1例,病变侧均出现锥体束信号异常,其中9例伴有同侧脑干体积缩小。结论:MRI诊断Wallerian变性有独特的优势和价值。

Abstract: | Objective: To study the MRI characteristics of Wallerian degeneration of the pyramidal tract involved in intracranial diseases,promote the recognition and diagnosis of this kind of degeneration. Methods: Twenty-three cases of Wallerian degeneration of the pyramidal tract involved in intracranial diseases were collected and all the MRI characteristics was analysed. Results: All the primary diseases were above the tentorium of cerebellum,of which 22 cases were located at one side of hemisphere and 1 case was demonstrated bilaterally. The abnormal signal of pyramidal tract was found at the same side of the primary disease,of which brain stems atrophy were found in 9 cases. Conclusion: MRI has large advantages and is quite valuable in the diagnosis of Wallerian degeneration. |
