Neurologic disease in glutaryl-CoA dehydrogenase (GCDH) deficiency usually presents with acute encephalopathic crises before 2 years of age. The authors report two previously asymptomatic patients with macrocephaly presenting with progressive neurologic deterioration and a severe leukoencephalopathy during adolescence or adulthood.
