Summary
X-linked adrenoleukodystrophy (X-ALD) can present with rare cerebellar symptoms, mimicking olivopontocerebellar atrophy. Early recognition of this neurological disorder is crucial for genetic counseling and treatment.
Area of Science:
- Neurology
- Genetics
- Biochemistry
Background:
- X-linked adrenoleukodystrophy (X-ALD) is a rare genetic disorder affecting the adrenal glands, nervous system, and gonads.
- Typically, X-ALD involves spinal cord degeneration and cerebral white matter lesions.
- Selective cerebellar white matter involvement is exceptionally rare in X-ALD.
Observation:
- A 29-year-old man with Addison's disease presented with progressive gait ataxia.
- Magnetic resonance imaging (MRI) showed significant cerebellar and brainstem atrophy, sparing supratentorial white matter.
- Clinical presentation and MRI findings resembled olivopontocerebellar atrophy.
Findings:
- Diagnosis of X-ALD was confirmed by elevated serum very long-chain fatty acids.
- The patient later developed spastic paraparesis, indicating disease progression.
- This case highlights an unusual X-ALD presentation with predominant cerebellar involvement.
Implications:
- Cerebellar symptoms, including ataxia, should be considered in the differential diagnosis of X-ALD.
- Early identification of this rare neurological disorder aids in genetic counseling and therapeutic interventions.
- Understanding atypical presentations improves diagnostic accuracy for X-ALD.
