Juvenile metachromatic leukodystrophy in a boy with epilepsy.

M leukodystrophy (MLD) is an autosomal recessive disorder, caused by deficiency of arylsulfatase A (cerebroside sulfatase A, ASA), which results in accumulation of sulfatides, mainly in the brain and peripheral nerves. The estimated frequency of MLD from previous reports is 1 in 40,000 cases. The deficiency in ASA activity is caused by mutations in the ASA gene. The deficiency is systemic and a...

MR of childhood metachromatic leukodystrophy.

PURPOSE To investigate the MR findings of childhood metachromatic leukodystrophy (MLD). METHODS Nine MR imaging studies in seven children (five girls and two boys, 10 to 32 months old) with MLD were evaluated retrospectively for the extent and progression of white matter abnormalities and the presence of contrast enhancement. RESULTS All seven cases showed symmetric, confluent high signal i...

Multi-Voxel 1H-MRS in Metachromatic Leukodystrophy

Metachromatic leukodystrophy (MLD) is characterized by the accumulation of sulfatide sphingolipids in the brain and peripheral nerves. We report metabolite alterations recorded using multi-voxel proton spectroscopy of the brain in four children with MLD. The data revealed elevated myoinositol/creatine and lactate/creatine ratios as well as decreased N-acetyl aspartate/creatine ratios. We propos...

Adult-type metachromatic leukodystrophy mimicking multiple sclerosis.

recessive lysosomal storage disease caused by a deficiency of arylsulphatase A (ASA). It is characterized by accumulation of sulphatide in the white matter in the central nervous system and peripheral nerves1. The disease is divided in four subtypes, according to onset, severity and progression of the disease: late infantile (before age 4), early juvenile (age 4 to 6), late juvenile (age 6 to 1...
