Findings:
Axial T1, coronal/axial PD, and axial T2WI show symmetric
abnormal signal in the globi pallidi.
Differential Diagnosis/Discussion:
History would be helpful to establish a reasonable differential.
The symmetric globus pallidus is nearly pathognomonic for carbon monoxide
poisoning. Liver disease may cause T1 hyperintensity. Hypoxic injury could
have a similar appearance.
