Multiple sclerosis-like syndrome in a woman heterozygous for adrenoleukodystrophy

A 28-year-old asymptomatic woman was diagnosed to be heterozygous for adrenoleukodystrophy (ALD) by elevated very long-chain fatty acids in serum and fibroblasts after ADL had been diagnosed in her son. A year later she had transient unilateral blurred vision. Evoked potentials and brain magnetic resonance imaging showed further separate cerebral white matter lesions suggesting multiple sclerosis (MS). MS-like syndromes in women heterozygous for ALD may be more frequent than previously recognized.
