Case of the Month #34 Carbon Monoxide Poisoning

Published 01/12/2022

What changes in brain imaging can be seen in CO poisoning?

CO poisoning can lead to changes within the central white matter of the brain (for example globus pallidus, putamen and caudate nucleus). MRI scanning can reveal further changes; in some patients a delayed leukoencephalopathy may occur over a number of weeks and in some cases this may resolve and improve.
