| Abstract |
To understand the clinical and pathological features of 1,2-dichloroethane (DCE) toxic encephalopathy.The cases of 4 patients who were admitted to Xiangya hospital between January 8, 2008 and November 8, 2012 with diagnoses of DCE toxic encephalopathy were examined. We recorded data on gender, age of onset, exposure time to DCE, symptom onset to admission interval, symptom onset to worst symptom experience interval, and clinical manifestations, as well as cranial magnetic resonance imaging (MRI) and brain biopsy pathology results.All 4 patients had a history of DCE exposure and presented with symptoms of intracranial hypertension. Cranial MRI revealed extensive brain edema throughout the subcortical white matter, the bilateral globus pallidus, and the cerebellar dentate nuclei. The brain biopsy confirmed severe cerebral edema, including peripherovascular edema, with swelling of various cell types, with extensive glial cell necrosis. After treatment with steroids and mannitol (3-10 weeks), all 4 patients recovered, partially or completely.Severe brain edema and extensive glial cell necrosis were the main pathological features observed in the present cases, with a likely etiology of DCE toxicity. Early, prompt, and long-term treatment with dehydrating agents and glucocorticoids was an effective treatment for this condition.
