摘要
目的探讨胼胝体压部(splenium of the corpus callosum,SCC)可逆性病变的MRI表现及临床特点。方法回顾性分析8例脑MRI表现为单纯胼胝体压部可逆性病变患者的临床和影像学资料。结果 8例患者的SCC可逆性病变均为继发性,原发病分别为脑内感染5例,肝豆状核变性、低血糖脑病及脑外伤各1例。8例患者均急性起病,临床表现为发热、头痛5例,急性意识障碍2例,肌张力增高2例,颈强2例,均符合原发病的临床表现。8例均行脑MRI检查,均表现为T1低或等信号,T2及FLAIR序列高信号,DWI高信号(提示细胞源性水肿),其中4例行增强扫描未见强化。8例患者均于临床症状好转或消失后复查MRI提示病灶消失。结论 SCC可逆性病变在多种疾病中均可出现,无该病变相关的特异性临床表现,MRI表现提示病灶为细胞源性水肿可能。
Objective To investigate the MRI findings and clinical features of reversible lesions in splenium of the corpus callosum（SCC）.Methods A retrospective analysis of clinical and imaging datawas adoptedamong 8cases with pure SCC reversible lesions.Results All SCC reversible lesions of8 patientswere secondary,the primary diseases were：intracranial infection（5 cases）,liver degeneration,hypoglycemia encephalopathy and traumatic brain injury（1case,respectively）.All patients had acute onsetand the clinical manifestationsincludingfever,headache（5cases）,acute disturbance of consciousness（2cases）,hypermyotonia（2cases）,neck stiffness（2cases）,were all in accordance with the primary diseases.8cases underwent brain MRI.MRI showed low or equal signals on T1 WI,high signalonT2 WI,FLAIRand DWI（suggested cell-derived edema）,there were no enhancement in 4patients＇enhanced scan.Follow-up MRI showed normalresultswhen clinical symptoms improved or disappeared in 8patients.Conclusions Reversible lesions of SCC can appear in a variety of diseases,and there are no specific clinical manifestations associated with the disease.MRI shows the lesions may becell-derived edema.
