We report a 10-year-old Down syndrome patient who developed dystonia, choreoathetosis, dysarthria, and dysphagia beginning with hemiparesis. Cranial computed tomography disclosed bilateral calcification in the globus pallidus which resembled a sign of premature aging. Conversely, the clinical course and magnetic resonance imaging findings resembled those of Hallervorden-Spatz syndrome.

The case of a 15 year old male patient with progressive dystonia, dysarthria and dementia is presented. No diagnosis could be found on clinical grounds. Low field MRI (0.23 T) demonstrated bilateral necrosis in the globus pallidus of clinically unknown etiology. Only high field imaging (2.0 T) revealed a pattern of lesions which is supposed to be specific for Hallervorden-Spatz disease (HSD): bilateral symmetrical decreased signal intensity in the globus pallidus secondary to the T2* effect of paramagnetic substances, principally iron. The neuroradiological differential diagnosis and pathognomonic signs of HSD are discussed.

A young child with Hallervorden-Spatz syndrome is presented. She was well until 8 years of age when she lost interest in activities and her school performance declined. At age 11 years, she began having episodes of blepharospasm, accompanied by bilateral ptosis and occasional episodes of oculogyric crisis. By age 12 years, her motor coordination had declined and she began to exhibit evidence of dementia, dystonia, dysarthria, and tremor. Motor incoordination, dystonia, and tremor progressed until the patient was wheel-chair-bound. Multiple tests were performed, including metabolic studies, magnetic resonance imaging, bone marrow biopsy, and electron microscopy of the buffy coat. Both bone marrow and buffy coat revealed inclusions in the cytosomes which were granular and osmiophilic. To our knowledge, this is the third case report of inclusion bodies found in patients with manifestations of Hallervorden-Spatz syndrome. These findings suggest that obtaining a buffy coat and bone marrow biopsy may aid in the diagnosis of Hallervorden-Spatz syndrome and ultimately provide information regarding etiology.

The case of a female patient with infantile onset of progressive dystonia, disturbance of gait and dysarthria is presented. At age 7, the diagnosis of Hallervorden-Spatz disease was established by clinical findings including retinal pigment degeneration, basal ganglia hyperdensity on CT, and the rare association of acanthocytosis. The clinical course was followed over 15 years until the patient's death.

The case of an 11-year-old female with the clinical findings of Hallervorden-Spatz syndrome, including progressive dystonia, dysarthria, disturbances of gait, and retinal pigmentary degeneration, is presented. The differential diagnosis of childhood dystonia and retinal pigmentary degeneration associated with neurological conditions is discussed. The presence of basal ganglia densities on computed tomography scanning in this patient may aid in future premortem diagnosis of this rare disease.

Magnetic resonance (MR) imaging of a case of Hallervorden-Spatz disease (HSD) using a 1.5 T system is described. The patient showed progressive spastic diplegia with equinovarus deformity of the feet, dystonic postural movements, dysarthria, dysphagia, mental deterioration, optic nerve atrophy, and peripheral neuropathy. These clinical features were compatible with HSD. Symmetrical, decreased signal intensity was seen on both proton density weighted and T2-weighted spin echo images in the globus pallidus as well as in the substantia nigra (Group I). This MR finding suggests an increased iron deposition in these subcortical nuclei, which is characteristic of HSD. The characteristic MR imaging, together with the relevant clinical features, was considered to be useful for establishing the diagnosis of HSD.

We describe an example of a variant of Hallervorden-Spatz disease, characterized by hypoprebeta-lipoproteinemia, acanthocytosis, retinitis pigmentosa, and pallidal degeneration (HARP syndrome), in an 18-year-old woman who presented with longstanding intellectual subnormality, night blindness, and a 2-year history of orobuccolingual dystonia causing dysarthria and dysphagia. Investigation showed acanthocytosis and hypoprebetalipoproteinemia, and electroretinograms were typical of tapetoretinal degeneration. T2-weighted MRI showed decreased signal intensity in the pallidal nuclei with central hyperintensity, constituting the "eye-of-the-tiger" sign. The patient's sister and mother have a similar lipid disorder but no retinal or neurologic disease. We also report two patients with clinical and radiologic features similar to those of the patient with HARP syndrome but who had normal lipid studies. These various combinations of components of HARP syndrome may be caused by several distinct genetic diseases or may represent variable manifestations of a contiguous gene defect.

Hallervorden-Spatz syndrome is generally considered to be an autosomal recessively hereditary disorder of unknown etiology. Some reported cases have been known to be sporadic. We present a boy who suffered from regressive developmental milestones since he was 2 years and 6 months old. He began to manifest tremors of the upper extremities, followed by unsteady gait, choreoathetosis, dystonia, dysarthria, and dysphagia at 4 years old, and subsequently became completely bedridden at 6 years old. Neurologically, opisthotonus, rigidity of extremities, dystonia, hyperreflexia, profound emaciation, and bilaterally positive Babinski signs were present. The brain magnetic resonance imaging (MRI) done at the age of 8 years revealed symmetrical low signal intensity over the bilateral globus pallidi in the T2-weighted images coexistent with an area of high signal intensity over the anteromedial portion, known as "eye of the tiger" sign. Another MRI, followed up two years later, did not show marked difference in signal abnormalities over the globus pallidi in the T2-weighted images as compared with that of the previous one. However, progressive neurological deterioration existed.

We report a 20-year-old female with Hallervorden-Spatz syndrome (HSS). This patient is the product of consanguineous parents. She developed genu valgum, tendency to fall and mental deterioration at the age of 6, decrease of the number of spoken words at the age of 14, dysarthria, unsteady gait, postural tremor of the upper extremities, dystonic posture of hands and double incontinence at the age of 16. Her disease progressed slowly. Neurological examination on admission revealed severe mental retardation, optic atrophy, forced grasping, hyperactive tendon reflexes in the upper extremities and bilateral Babinski sign. An extensive laboratory investigation including the leukocyte lysosomal enzymes, serum amino acid analyses, copper studies and ceruloplasmin were almost within normal limits. MRI, T2 weighted images, showed markedly decreased signal intensity in the globus pallidus but substantia nigra and increased signal intensity in diffuse cerebral white matter. T1 weighted images showed marked atrophy of the brainstem and cerebellum. She met the diagnostic criteria for HSS by Swaiman; we diagnosed her as HSS group II. HSS is characterized by the presence of many spheroids in the central nervous system which is similar to neuroaxonal dystrophy (ND). However, clinical and pathological differences exist between HSS and ND, the precise classification of the two conditions has remained controversial. Although there are many reported cases in which both conditions overlap, this is the first reported case that simultaneously demonstrates increased iron deposition in the globus pallidus, marked atrophy of the brainstem and cerebellum and typical clinical course compatible with HSS.

Hallervorden-Spatz disease (HSD) is an extremely rare degenerative process. The familial studies point to inherited, autosomal recessive neurodegenerative disorder. Quite recently this disease gene has been identified to chromosome 20p12.3-p13. Clinical manifestations of HSD leading to death after several years of illness are most frequently observed in childhood. HSD in adults is very scarce. The case reported concerns a woman who at the age of 26 years began to suffer from slowly progressing psycho-organic syndrome with muscular rigidity, involuntary movements and dysarthria. The patient was hospitalized several times with successive diagnoses of multiple sclerosis, amyotrophic lateral sclerosis and Huntington's disease. Shortly before death magnetic resonance imaging (MRI) scan showed a decreased signal in both basal ganglia. The patient died at the age of 34 years after an eight-year illness. In the brain autopsy symmetric hyperpigmentation of globus pallidus (GP) and reticular part of substantia nigra (SN) was found. The microscopic observation revealed abundant deposits of brown pigment mostly in GP and SN. In addition, numerous spheroids disseminated in the basal ganglia, mesencephalon and medulla oblongata, as well as Lewy bodies in SN were noted. Pigment deposits expressed intensive iron positive reaction by Perls' Prussian-blue method. Based on the described neuropathological changes occurring mostly in GP and SN, Hallervorden-Spatz disease was diagnosed.
