摘　　要：缺血性卒中后沿同侧锥体束的DWI高信号是沃勒变性(Wallerian degeneration,WD)主要的影像学表现之一,但在临床上易被漏诊或误诊为新发梗死。本文报道了1例缺血性卒中患者发病2周后所发生的锥体束急性WD,分析其头颅核磁影像中DWI与弥散张量成像的变化,并通过纤维追踪技术重建锥体束模型,实现可视化分析,以期为疾病诊断提供新的思路与方法。Hyperintensity on DWI along the ipsilateral pyramidal tract after ischemic stroke is one of the main imaging manifestations of Wallerian degeneration(WD),but it is easily missed or misdiagnosed as a new infarction in clinical practice.This paper reports a case of acute WD of pyramidal tract that occurred two weeks after ischemic stroke,analyzing the changes in DWI as well as diffusion tensor imaging,and reconstructing the pyramidal tract model through fiber tracking technology for visual analysis.It aims to provide new insights and methods for the diagnosis of the disease.
