Two families are presented in which siblings of children affected with Hallervorden-Spatz syndrome exhibited characteristic cranial magnetic resonance imaging changes before developing clinical features of the disease. Linkage to a major locus on chromosome 20p supported the diagnosis of Hallervorden-Spatz syndrome. In some patients with Hallervorden-Spatz syndrome, iron is radiographically evident before the onset of clinical symptoms.
