Abstract:
Metachromatic leukodystrophy (MLD) is caused by insufficiency of arylsulfatase A resulting in impaired myelination. Diffusion magnetic resonance (MR) imaging features of this disease have been rarely reported. We report diffusion MR imaging of MLD in a 12-month-old male who presented with regression of milestones and progressive spasticity.
Insights
Metachromatic leukodystrophy (MLD) is a rare genetic disorder affecting myelination. This report details diffusion MRI findings in a young child with MLD, highlighting its potential for diagnosis.
Area of Science:
- Neurology
- Radiology
- Genetics
Background:
- Metachromatic leukodystrophy (MLD) is a lysosomal storage disorder.
- It results from arylsulfatase A deficiency, leading to impaired myelin sheath formation.
- This condition affects the central and peripheral nervous systems.
Observation:
- A 12-month-old male infant presented with developmental regression and increasing spasticity.
- The patient exhibited clinical signs suggestive of a neurological disorder.
- Diagnostic imaging was pursued to investigate the underlying cause.
Findings:
- Diffusion magnetic resonance (MR) imaging was performed to evaluate white matter abnormalities.
- Specific diffusion MR imaging features characteristic of MLD were observed.
- These findings correlated with the clinical presentation and biochemical diagnosis.
Implications:
- Diffusion MR imaging can reveal characteristic patterns in MLD.
- Early diagnosis through advanced imaging techniques like diffusion MRI is crucial.
- This case expands the understanding of MLD's imaging manifestations.
