CT findings of the interval form of carbon monoxide poisoning compared with neuropathological findings.

Cerebral computed tomography findings were described in 2 clinical cases of the interval form of carbon monoxide poisoning and comparison with postmortem CT finding of an autopsy case was made. There was low density in the bilateral frontal region, centrum semiovale and pallidal parts. In the course of the disease, the degree of low density in the white matter showed a tendency to diminish but it became more apparent in the pallidal parts. Myelinopathic white matter lesion in an autopsy material was recognized as a low density area in CT, which is identical with that seen in clinical cases.
