摘要
Hallervorden-Spatz syndrome is a neurodegenerative disease, autosomic recessive with two clinical features: early and late onset. Psychiatric, pyramidal and extrapyramidal signs are present in the late subtype. We report the case of a 41-old woman with extrapyramidal signs. Magnetic resonance imaging (MRI) showed the eye-of-the-tiger sign in the medial globus pallidus. This is due to a gliosis (increased signal) and accumulation of surrounding iron (decreased signal intensity) in long TR sequences. There is a strong relationship between MRI findings and the gene mutation responsable for this disease. It makes the MRI sensible for diagnosing this syndrome.
