title: [A 26-year-old woman of interval form of acute carbon monoxide intoxication with cerebrospinal fluid abnormalities].
abstract: A 26-year-old woman was admitted to our hospital for the treatment of hyperbaric oxygen therapy to acute carbon monoxide intoxication. The consciousness disturbance improved and she was discharged after 23 times of the hyperbaric oxygen therapy. However, she was readmitted because of dementia and urinary incontinence after 22 days. Diffusion-weighted images showed bright high signal intensities in the periventicular white matter and corpus callosum. The condition was considered to be an interval form of carbon monoxide intoxication. She was treated by 38 times of the hyperbaric oxygen therapy with cytochrome C and fully recovered. MRI images and cerebrospinal fluid abnormality (high protein content and IgG index) became normalized somewhat later than the improvement of the symptoms. By an investigation utilizing diffusion-weighted images, we thought that not only the demyelination which mentioned formerly, but the vasogenic edema was involving in the mechanism of these high signal intensities in the periventicular white matter of the interval form. And in the range which we searched, this is the first report which mentioned the abnormal findings of cerebrospinal fluid in an interval form of carbon monoxide intoxication. So we believe this case is very important for telling us suspected the mechanism and some indications about the treatment of an interval form.
