Overview
MRI findings in CJD include high signal abnormalities in caudate nucleus and/or putamen on diffusion-weighted imaging (DWI) or fluid attenuated inversion recovery (FLAIR).[1] Additional findings on diffusion weighted imaging include cortical, subcortical, and thalamic involvement.
MRI
- MRI often shows high signal intensity in the caudate nucleus and putamen bilaterally on T2-weighted images.
- Diffusion Weighted Imaging (DWI) images may be remarkable for the following findings:[2]
- Cortical hyperintensity (25%-70% of cases)
- Subcortical abnormalities (5% of cases)
- Thalamic involvement, usually in posterior thalamus (more strongly associated with variant Creutzfeldt-Jakob disease than with classic Creutzfeldt-Jakob disease)[3]
