【摘要】：正患者女,22岁,无明显诱因出现说话不清3天,未治疗,遂于本院就诊,行头部MRI平扫、增强及磁共振波谱(MRS)扫描。左侧额叶可见团片状长T1信号(图1),稍混杂T_2信号(图2、3),T_2WI局部放大示短T_2信号(图3白箭),FLAIR序列呈稍高信号(图4),周围可见片状长T_2水肿信号,DWI高b值(1000 s/mm~2)可见环状或片状扩散受限呈高信号(图5),ADC图呈低信号。静注钆喷酸葡胺注射
[Abstract]:The female patient, 22 years old, had no obvious inducement to speak for 3 days without treatment, so she went to see a doctor in our hospital and underwent MRI plain scan of her head. Enhancement and MRS scan. Long T 1 signal in left frontal lobe (Fig. 1, slightly mixed with T _ 2 signal) (figure 2 / 3 / T _ 2WI local amplification shows short T _ 2 signal (fig. 3) flair sequence is slightly hyperintense (fig. 4), flaky long T _ 2 signal can be seen around. Edematous signal intensity / DWI high b value / 1000 s / mm / 2) high signal intensity can be seen in circular or flake diffusion limited (fig. 5) ADC map shows low signal intensity.
