摘要
目的分析瘤样炎性脱髓鞘病(TIDD)临床、影像与病理特点,探讨磁共振(MRI)检查对TIDD的诊断价值。方法对39例TIDD患者进行头颅、脊髓CT和MRI扫描,并分析临床和影像学特点。结果病灶在头颅CT均为低密度,常规MRI扫描呈T1WI低信号、T2WI高信号,T1WI增强扫描44%可见"开环征",发病早期DWI可见高信号,FLAIR较T1WI及T2WI更清晰显示病灶及其范围。结论 DWI能发现TIDD早期病变,FLAIR较常规T1WI、T2WI敏感,"开环征"是磁共振诊断TIDD的重要辅助依据。
Objective To analyze the clinical manifestations,imaging and pathological characteristics of tumor-like inflammatory demyelinating diseases(TIDD).To evaluate the role of magnetic resonance imaging(MRI)in the diagnosis with TIDD.Methods 39 patients of TIDD were studied on MRI and/or CT scan and summarized the characteristics.Results Lesions of all cases were showed hypointense signal on CT scan and T1 Weighted Imaging(T1WI)of MRI,and hyperintense signal were showed on T2 Weighted Imaging(T2WI).Lesions could ...
