N2 - Fucosidosis is a rare autosomal recessive lysosomal storage disease, resulting from a deficiency of alpha- L-fucosidase. We report on the clinical and MRI findings of a girl with this disorder. Developmental delay became obvious at an age between 6 and 12 months. Cranial MRI at 16 months revealed severe global hypomyelination of both supra- and infratentorial white matter but no involvement of basal ganglia or thalamus. No clinical signs typical for fucosidosis were present at this time, and psychomotor development still progressed slowly. Since the age of 2 years, progressive neurological deterioration occurred. The diagnosis was established by severely decreased activity of alpha- L-fucosidase in plasma and leukocytes and confirmed by the detection of compound heterozygosity for two missense mutations of the FUCA1 gene. A follow-up imaging at the age of 4 years showed progression of neuroradiological abnormalities, particularly progressive involvement of basal ganglia and thalami. The course of this patient and her MRI findings enlarge the clinical and neuroradiological spectrum of fucosidosis.
