Abstract
Serial magnetic resonance (MR) images mere obtained for 18 months in t he follow-up oi a patient with delayed encephalopathy after acute carb on monoxide (CO) poisoning. The characteristic findings on T2-weighted MR images (T2WI) were high intensity in the bilateral periventricular white matter and pallidal regions, and low intensity in the striatum. Although the neurological symptoms had improved by about 5 months aft er exposure, the high signal intensity ill the white matter remained v isible for 18 months. In addition, low signal intensity in the putamen seen on T2WI, which suggested iron deposition, was seen throughout th e 18 months.
