Childhood neuromuscular disease with rimmed vacuoles

1986

A 5-year-old boy suffered from a slowly progressive non-familial neuromuscular disease, clinically marked by generalised muscle weakness, atrophy and hypotonia, a "myopathic" EMG and mildly elevated CK values. His gastrocnemius muscle showed marked myopathy, type I fibre predominance, and numerous "rimmed" vacuoles. This boy's condition is regarded as a childhood neuromuscular disease with rimmed vacuoles.
