Abstract

We report clinical features, CT-scan and MRI findings of three siblings with Hallervorden-Spätz disease, one of them followed for more than 20years. Patient 1 presented at age 10 with progressive generalized dystonia. Five years later she had violent dystonic spasms with opisthotonos and marked oro-mandibular involvement. Later, dystonia stabilized and examination showed dysarthria, multiple deformities related to dystonic posturing, retinal degeneration and no cognitive impairment. Cerebral CT-scan showed bilateral pallidal lucencies and T2 cerebral MRI showed the "eye of the tiger" sign.Patient 2 developed delusions and hallucinations at age 18 with acute phases of hetero-aggressivity diagnosed as "schizophrenic" in a psychiatric hospital. At age 20, he developed oromandibular dystonia, severe dysarthria and epilepsy. Cerebral MRI showed the same "eye of the tiger" sign.Patient 3 presented at age 37 with isolated psychiatric features similar to those of patient 2, also diagnosed "schizophrenic" in a psychiatric hospital. Neurological examination showed mild postural tremor of the hands and intermittent cervical dystonia. He was stabilized with neuroleptic treatment.This family shows marked intrafamilial variability of age at onset, symptom at onset (with "schizophrenic" features unusually described and leading to misdiagnosis), clinical presentation (almost entirely dystonic in one patient and almost entirely psychiatric in two others) and course of the disease (slowly progressive in one sibling, rapidly deteriorating in the second and stabilization in the third). Classification and nosology of subtypes of HSD are discussed.
