Summary
X-linked adrenoleukodystrophy (X-ALD) can mimic spinocerebellar ataxia, presenting with unique cerebellar white matter disease. Early X-ALD diagnosis is crucial for managing this rare variant.
Area of Science:
- Neuroscience
- Genetics
- Endocrinology
Background:
- X-linked adrenoleukodystrophy (X-ALD) exhibits diverse phenotypes.
- Spinocerebellar degeneration is a rare presentation of X-ALD.
- Selective cerebellar white matter involvement is exceptionally uncommon.
Observation:
- A 24-year-old male with delayed milestones and Addison's disease developed spinocerebellar degeneration.
- MRI revealed cerebellar and pontine white matter disease, sparing supratentorial regions.
- Elevated very long chain fatty acids confirmed X-ALD diagnosis.
Findings:
- The patient's presentation mimicked spinocerebellar ataxia.
- Distinct MRI findings highlighted selective white matter disease.
- This case underscores the phenotypic variability of X-ALD.
Implications:
- Highlights the importance of considering X-ALD in spinocerebellar degeneration differential diagnoses.
- Early recognition facilitates genetic counseling and timely therapeutic interventions.
- Potential for improved patient outcomes through prompt diagnosis and management.
