ABSTRACT
PURPOSE:
In this study, a case of toxic encephalopathy and optic neuropathy due to methyl bromide poisoning is reported. CASESUMMARY:
A 31-year-old male presented with dysarthria, gait disturbance and bilateral visual impairment. He was treated with intravenous methylprednisolone for bilateral optic neuritis 1 year prior. He previously worked in a fumigation warehouse and was exposed to methyl bromide in the past 3 years. His corrected visual acuity was 20/30 in both eyes. The patient had reduced color vision and enlarged central scotoma in both eyes. His mentality was alert but exhibited slow response, ataxia and dysarthria. Brain magnetic resonance imaging (MRI) revealed high signals in the brainstem, cerebellum and midbrain. His serum and urine methyl bromide concentrations were significantly elevated. The patient was treated with intravenous methylprednisolone 1.0 g/day for 5 days. MRI showed resolution of the multiple brain lesions observed previously. Ten days after steroid therapy, his visual acuity was 20/20 in both eyes and his neurologic manifestations were completely recovered at 2 months after treatment.CONCLUSIONS:
Taking a detailed occupational history is necessary in patients with optic neuropathy. The probability of toxic optic neuropathy should be considered when patients are exposed to toxic materials.
