Demographics:
57 years old, Female
Indication:
Altered mental status
Findings
- Symmetric abnormal signal involving the bilateral globi pallidi including central T1/T2 isointensity with peripheral T2/FLAIR hyperintensity, thin discontinuous peripheral T1 hyperintensity, and peripheral enhancement
- Punctate focus of restricted diffusion in the left globus pallidus
- Patchy areas of enhancement in the medial left and inferior right cerebellar hemispheres with corresponding faint areas of T2/FLAIR hyperintensity
- No intracranial mass effect, acute hemorrhage, or hydrocephalus
Diagnosis
Carbon monoxide toxicity
Sample Report
Symmetric abnormal signal in the bilateral globi pallidi with associated peripheral enhancement as well as patchy enhancement involving the bilateral cerebellar hemispheres, for which the primary differential considerations are a toxic/metabolic process (including carbon monoxide poisoning, cyanide toxicity, and illicit drug use) and subacute infarcts.
