Abstract: BACKGROUND: 1,2-dichloroethane (DCE) induced toxic encephalopathy, a rare toxic disease of the central nervous system, is mainly reported in developing countries. Although clinicians have got some understanding about the clinical and neuroimaging features of 1,2-DCE-induced toxic encephalopathy, abnormality along the cortico-medullary junction on diffusion-weighted image (DWI) mimicking neuronal intranuclear inclusion disease (NIID) has not yet been described in this entity. CASE PRESENTATION: We reported a patient with 1,2-DCE-induced toxic encephalopathy who was admitted to our department due to a 7-day history of nausea, vomiting, and cognitive decline. Brain magnetic resonance imaging (MRI) showed symmetrical hyperintensities in bilateral subcortical white matte on T2-weghted and Fluid-attenuated inversion recovery (FLAIR) images. In addition, abnormal signal intensity could also be found in the cortico-medullary junction on DWI, mimicking NIID. After treated with glucocorticoid, dehydrating agents, neuroprotective agents, and hyperbaric oxygen, our patient received a partial recovery. CONCLUSION: Our case highlights a special MRI finding-abnormalities along the cortico-medullary junction-that can be seen in 1,2-DCE-induced toxic encephalopathy. When confronted with patients with lesion located in the cortico-medullary junction and neuropsychiatric symptoms, our clinicians should not neglect the detailed inquiry of history of toxic exposure.
