【摘要】 目的探讨海洛因中毒性海绵状脑白质变性的CT和MRI的表现。方法结合文献回顾性分析6例海洛因中毒性海绵状脑白质变性者的CT和MRI资料。结果全部病灶都位于脑白质内,呈多形性、对称性分布。CT为低密度,MRI为长T1、T2信号,边界清楚或模糊,增强无强化。MRI诊断本病明显比CT优越,共显示大脑病灶55个,中脑病灶4个,小脑病灶8个。结论海洛因中毒性海绵状脑白质变性的CT和MRI表现颇具特点,结合吸毒史和中枢神经症状,不难与其他脱髓鞘疾病鉴别诊断。更多还原

【Abstract】 Objective To study CT and MRI findings of the spongiform myelinopathy in poisoning by heroin.Methods CT and MRI findings in 6 patients with spongiform myelinopathy in poisoning by heroin were retrospectively analyzed with review of literature.Results The lesions were located in white matter,they were multiform and symmetrically distributed.On plain CT scans,the lesions were low density.On MRI,the lesions were low signal on T1WI and high signal on T2WI.The border of lesions was clear or not and no enhancement appeared.MRI is precedent of CT in the diagnosis of this disease,totally 55 focal lesions in the brain ,4 in midbrain and 8 in cerebellum were displayed by MRI.Conclusion CT and MRI findings of the spongiform myelinopathy in poisoning by heroin are more characteristic,according to the drug taking history and central nervous system symptom of patients,differentiating this disease from the other demyelinating disease is not difficult.更多还原
