다국어 초록 (Multilingual Abstract)

The carbon monoxide (CO) intoxication has occurred not infrequently in the Korea. Presently, it is well known that there are neurological and complications after CO intoxication. The delayed neurological sequelae of CO intoxication may be also occurred for days or weeks after anoxic exposure. Common delayed neurological manifestations include diffuse cortical dysfunction, psychotic behavior, dementia, parkinsonism, and peripheral polyneuropathy. On magnetic resonance imaging, bilateral symmetric confluent high signal intensity in the periventricular white matter and centrum semiovale was seen on long-repetition-time images, and bilateral ischemia or necrosis of the globus pallidus was seen. The outcome of these sequelae relatively good. We report two cases of delayed postanoxic encephalopathy after acute CO intoxication. Their clinical manifestations were decreased mentality, disorientation, memory disturbance, spasticity and mutism.
