摘 要: | 目的:寻找提示神经梅毒的MRI表现的特点。方法:回顾性分析8例经临床证实的神经梅毒患者的MRI表现,并归纳其特点。结果:所有患者MRI表现为病变广泛弥散,至少累及2个脑叶以上,表现为T1WI低信号,T2WI高信号影,FLAIR上呈高信号。5例同时累及幕上、幕下,6例累及灰白质,所有病例DWI呈等或稍高信号影,均存在脑萎缩征象。其中5例行增强扫描,所见病变均未见明显强化。结论:MRI表现:同时累及幕上、幕下及灰白质,DWI上为等或稍高信号及同时合并脑萎缩,增强扫描未见明显强化者,应注意排除神经梅毒。

Abstract: | Objective Searching for the characteristic of MRI referring to the neurosyphilis. Methods Retrospective analysis the MRI present of 8 cases of neurosyphilis and sum up their characteristic. Result The lesions of all cases distributed dispersion in MRI and involved two lobes at least. They showed low signal intensity in T1 weight imagine, high signal intensity in T2 weight imagine and FLAIR. 5 cases involved supratentorial ang subtentorial structure simultaneously. 6 cases involved gray and white matter. All lesions showed normal or a little high signal intensity in DWI No gadolinium - enhancing lesions was found in 5 cases which were performed enhancement scanning. All the cases showed cerebral atrophy. Conclusion The neurosyphilis should be eliminated when MRI shows : the lesions involving supratentorial ang subtentorial structure simultaneously, involving gray and white matter, normal or a little high signal intensity in DWI, no gadolinium - enhancing lesions, cerebral atrophy. |
