Abstract:
Abnormal high signal in the corticospinal tracts on MRI has been described in amyotrophic lateral sclerosis. We report a case with further high signal in fibres of the corpus callosum on proton density and T2-weighted spin-echo images, closely matching findings of earlier pathological reports.
Insights
Abnormal MRI signals in corticospinal tracts are linked to amyotrophic lateral sclerosis. This case also shows high signals in the corpus callosum, aligning with prior pathological findings.
Area of Science:
- Neurology
- Neuroimaging
- Pathology
Background:
- Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease.
- MRI is a key tool for diagnosing and understanding ALS.
- Corticospinal tract abnormalities on MRI are recognized in ALS.
Observation:
- This report details a specific case of ALS.
- The patient presented with abnormal high signal intensity in the corticospinal tracts on MRI.
- Additionally, high signal intensity was observed in the corpus callosum fibers.
Findings:
- The observed high signal in the corpus callosum was visualized using proton density and T2-weighted spin-echo MRI sequences.
- These imaging findings correlate closely with established pathological reports in ALS.
- This suggests a potential pattern of white matter involvement beyond the corticospinal tracts.
Implications:
- This case expands the understanding of MRI findings in ALS.
- It highlights the potential utility of specific MRI sequences in detecting broader white matter changes.
- Further research may elucidate the pathological basis and clinical significance of these corpus callosum findings in ALS.
