Carbon Monoxide Poisoning - infarctions in globi pallidi


82 years old admitted with signs of intoxication, history of suicide attempt. NECT shows symmetric low density oedematous globi pallidi (GP) - compared to old CT.




Note low density in globi pallidi on the admission NECT compared to old CT. 



MR exam has shown diffusion restriction in globi pallidi (high signal in GP on this rather dark DWI and low signal on ADC) corresponding with acute infarctions.



FLAIR and T2 show oedema in globi pallidi corresponding with acute infarctions. 




Contrast enhanced T1 sequence (right) shows a very subtle enhancement in both globi pallidi consistent with blood-brain barrier damage.
