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 T1WI and high signal on T2WI.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.
