We report the case of a 56-years-old woman patient, born to unrelated parents, who since 26-years-old gradually developed bradykinesia, rigidity, tremor of both hands, and speech and gait difficulties. Her past history was unremarkable. There was no family history of neurologic disease. She was admitted to our Hospital at age 39 and at that time she presented a full parkinsonian syndrome. The following tests were normal or negative: routine blood studies, serum copper, ceruloplasmin and cerebrospinal fluid examination. There was not Kayser-Fleicher ring, and fundoscopic examination revealed no abnormalities. Levodopa was introduced and response was good for more than ten years, despite early-onset of dyskinesias (three months after the introduction of the drug). After 30 years under levodopa she still presents a moderate response but with severe fluctuations of the motor performance. Except for slowness of cognition she developed no other neuropsychological impairments, and a recent neurological examination disclosed no abnormalities besides a parkinsonian syndrome. One year ago, a magnetic resonance imaging (MRI) was performed and showed bilateral, symmetrical lesions with "eye-of-the-tiger" pattern. This case illustrates the pathological heterogeneity of early-onset parkinsonism and suggests the possibility to find the typical MRI lesions seen in Hallervorden-Spatz disease in other degenerative affections involving globus pallidus.
