[Neurologic sequelae in severe carbon monoxide poisoning--case report].

The symptoms and clinical course of severe acute poisoning with carbon monoxide in 22-years-old man is described. To evaluate neurological sequelae, magnetic resonance imaging (MRI) repeatedly was performed. In initial examination, at week 7 after intoxication, MRI showed bilateral abnormalities of the amygdaloid nucleus, caudate nucleus and in globus pallidus at right.
