Abstract:
To investigate a possible relationship between the severity of pathological and radiological lesions in diffusion-weighted MRI (DWI) we compared DWI findings from 6 sequential brain MRI scans with pathological features of numerous tissue blocks of different cortical and subcortical regions in a case of autopsy-proven sporadic CJD. Whereas DWI and pathological examination revealed multifocal, cortical and deep hyperintensities at corresponding localizations, no correlation between the degree of severity of radiologically visible and pathological damage was found. The characteristic focal involvement and extension of lesions of the cortex and the basal ganglia bilaterally shown by DWI may be an argument for the spreading of the disease per contiguitatem.
Insights
This study compared diffusion-weighted MRI (DWI) findings with pathology in a Creutzfeldt-Jakob disease (CJD) case. No direct correlation was found between lesion severity on MRI and pathological damage.
Area of Science:
- Neurology
- Neuroimaging
- Pathology
Background:
- Investigating the relationship between radiological and pathological lesion severity in neurodegenerative diseases.
- Utilizing diffusion-weighted MRI (DWI) for assessing brain damage.
- Examining autopsy-proven sporadic Creutzfeldt-Jakob disease (CJD).
Observation:
- Compared DWI findings from 6 sequential brain MRI scans with pathological features from numerous tissue blocks.
- Examined cortical and subcortical regions in a sporadic CJD case.
- Identified multifocal, cortical, and deep hyperintensities on DWI at corresponding localizations to pathological findings.
Findings:
- No direct correlation was found between the severity of radiologically visible lesions on DWI and the degree of pathological damage.
- DWI revealed characteristic focal involvement and lesion extension in the cortex and basal ganglia bilaterally.
- Disease spread 'per contiguitatem' (by contiguity) is suggested by the pattern of DWI lesions.
Implications:
- DWI findings in CJD may reflect disease spread patterns rather than direct severity correlation.
- Further research is needed to understand the relationship between imaging and pathology in CJD.
- This study highlights the utility of DWI in visualizing the spatial distribution of CJD pathology.
