Abstract:
Objective To explore the clinical features, characteristics of neuroimaging and prognosis of toxic encephalopathy induced by 1,2- Dichloroethane. Methods The clinical features,characteristics of neuroimaging and prognosis in eight cases with toxic encephalopathy induced by 1,2- Dichloroethane were analyzed retrospectively. Results In acute or subacute stage of toxic encephalopathy induced by 1,2- Dichloroethane, the whole brain injury symptoms and severe intracranial hypertension were the main neurological manifestations. CT and MR examination showed diffused encephaledema and brain swelling. DWI test showed the symmetric diffused low density lesions in white matter of cerebral hemisphere,and the average values of ADC decreased significantly. With the disease improving, the brain swelling was alleviated, the brain lesion foci reduced gradually, and the average values of ADC increased. The prognosis will be improved dramatically if sufficient mannitol, hormone and high pressure oxygen were used in the early stage. Conclusion The diagnosis of toxic encephalopathy induced by 1,2- Dichloroethane depends mainly on the clear toxicant contact history, clinical features and characteristics of neuroimaging. Taking effective measures in the early stage to control actively the encephaledema would be beneficial to the prognosis.
