Metachromatic leukodystrophy, a group of progressive degenerative neurologic disease with variable age of onset characterized by an autosomal recessive mode of inheritance, shows an accumulation of the sphingolipid, sulfatide, particularly in the Schwann cell of the central and peripheral nervous system by arysulfatase A deficiency. 2 cases of late infantile metachromatic leukodystrophy are reported, who developed normally during a infantile period, but after that, occurred gait disturbance gradually and became in bedridden state and dementia. The Sural nerve biopsy revealed yellowish brown metachromatic granule in cresyl violet staining under acid pH, and cytoplasmic inclusions in Schwann cells by the electron microscopic finding.
