title: Follow-up magnetic resonance imaging in Hallervorden-Spatz disease.
abstract: Bilateral high signal emitting areas in the globus pallidus surrounded by low signal emitting areas have been described as a typical MRI finding in Hallervorden-Spatz disease (HSD). We made a diagnosis of HSD in an 11-year-old girl with progressive dystonia of 4 years duration who showed these typical MRI abnormalities. An initial MRI at the age of 9 was normal. Pathological confirmation of these typical MRI findings has not yet been described, but earlier reports as well as our case suggest that MRI may be helpful in making a clinical diagnosis of HSD. This case further shows that MRI may be normal in an early stage of the disease.
