Summary
Early-onset Krabbe disease in an infant presented with normal brain scans but abnormal spinal MRI findings. This spinal MRI enhancement pattern, typically seen in Guillain-Barré syndrome, is novel for leukodystrophies.
Area of Science:
- Neuroscience
- Radiology
- Pediatric Neurology
Background:
- Krabbe disease is a severe genetic disorder affecting myelin breakdown.
- It leads to progressive demyelination in the central and peripheral nervous systems.
- Early diagnosis is crucial for managing this rare leukodystrophy.
Observation:
- A 7-month-old infant with early-onset Krabbe disease was evaluated.
- Head MRI scans appeared normal, showing no significant abnormalities.
- Spinal MRI revealed abnormal gadolinium enhancement in the lumbosacral nerve roots and cauda equina.
Findings:
- The observed spinal MRI enhancement pattern mimicked Guillain-Barré syndrome.
- This specific enhancement in spinal MRI has not been previously documented in Krabbe disease or other leukodystrophies.
- The findings highlight a potential new imaging biomarker for Krabbe disease.
Implications:
- This case suggests spinal MRI may reveal abnormalities in Krabbe disease even with normal brain imaging.
- The findings expand the understanding of imaging manifestations in leukodystrophies.
- Further research is warranted to validate these spinal MRI findings in a larger cohort of Krabbe disease patients.
