【摘要】：正患者男,28岁,1月余前无明显诱因感持续性头痛,CT检查见右颞顶部椭圆形高密度影。后于我院行脑MR检查:右侧额、顶、颞、枕部硬脑膜不同程度增厚,以额部明显,局部呈不规则团块状长T1稍长T2信号,T2FLAIR序列呈稍高信号(图1A),DWI可见不均匀轻度弥散受限(图1B)。病变向内与邻近脑组织分界不清,向外局部侵犯颅板并部分突破颅板向头皮下生长。增强扫描见右额部病变不均匀明显强化,右侧额、顶、颞、枕部脑膜增厚强化(图1C)。患者接受右额部肿块切除术,
[Abstract]:Male patient, 28 years old, had no obvious inducement of persistent headache before 1 month. CT examination showed high density right temporal parietal ellipse. The right frontal, parietal, temporal and occipital dura mater were thickened to different degrees, especially in the frontal part, with irregular lumps of long T1 and slightly longer T2 signal intensity, and slightly higher signal intensity in T2FLAIR sequence (Fig. 1A), the right frontal, parietal, temporal and occipital dura mater were thickened in different degrees. DWI showed uneven slight dispersion limitation (Fig. 1B). The lesion was indistinguishable from the adjacent brain tissue and invaded the cranial plate locally and partly penetrated the cranial plate and grew under the scalp. Contrast-enhanced scan showed that the lesions of the right frontal region were significantly enhanced and the right frontal, parietal, temporal and occipital meninges thickened and enhanced (Fig. 1C). The patient underwent a resection of the right frontal mass,
