11例可逆性胼胝体压部病变综合征MRI表现及临床特点

Magnetic Resonance Imaging and the Clinical Features of Reversible Partial Pressure Syndrome of Corpus Callosum

目的分析可逆性胼胝体压部病变综合征(reversible spleninal lesin syndrome,RESLES)的MRI表现及临床特点。方法回顾性分析11例可逆性胼胝体压部病变综合征患者的MRI表现及临床特征。所有患者均在CT检查后进行MRI检查,治疗后应用MRI再次对病变区进行复查。结果 11例患者经CT检查均未发现明显阳性征象,11例患者24 h内MRI平扫检查表现为胼胝体压部椭圆形或者类圆形稍长T1T2信号病灶,FLAIR序列均呈现稍高信号,DWI呈现高信号,ADC呈现低信号,7例增强扫描呈现无强化表现。结论可逆性胼胝体压部病变综合征的临床症状无特异性,但具有特征性影像学表现,MRI影像学检查结果可作为RESLES的临床治疗的有利指导依据。

Objective To analyze the MRI features and the clinical features of reversible corpus callosum disease syndrome.Methods The MRI findings and clinical features of 11 patients with reversible corpus callosum disease syndrome were retrospectively analyzed.All patients were examined with MRI after CT,and the lesion area was examined again with MRI after treatment.Results All the 11 patients had no obvious positive signs after CT examination.Within 24 hours the patients’MRI plain scan,the lesions of corpus callosum were oval or round with slightly longer T 1T 2 signal,FLAIR sequence showed slightly higher signal intensity,DWI showed high signal intensity,ADC showed low signal intensity,and 7 cases showed no enhancement on enhanced scan.Conclusion The clinical symptoms of reversible corpus callosum disease syndrome are not specific and have characteristic imaging manifestations.MRI imaging results can be used as a good guide for the clinical treatment of reversible corpus callosum disease syndrome.
