What Researchers Did
Researchers reported the neurologic and radiologic manifestations of three adolescent girls who survived acute carbon monoxide poisoning.
What They Found
All three girls developed evolving neurologic manifestations including visual deficits, confusion, and focal motor weaknesses after acute carbon monoxide poisoning. Cerebral computed tomography showed focal infarctions in one patient, magnetic resonance imaging revealed cortical lesions in all three, and [18F]Fluorodeoxyglucose positron emission tomography detected decreased metabolism in the basal ganglia in two patients. Neurologic deficits resolved completely at 3 weeks, but psychologic symptoms followed.
