Carbon monoxide poisoning: Bilateral lesions in the thalamus on MR imaging of the brain

Abstract
Magnetic Resonance (MR) Imaging of the brain in a child with carbon monoxide poisoning revealed bilateral diffuse high signal in the centrum semiovale and the previously unreported finding of bilateral high intensity lesions in the anterior thalami. This case illustrates a previously unrecognized effect of carbon monoxide poisoning and demonstrates the superiority of MR imaging over computed tomography in cases of carbon monoxide poisoning.
