Hallervorden-Spatz syndrome (HSS) is a neurodegenerative disorder characterized by progressive dementia, dystonia, ataxia, and rigidity. An atypical form of adult-onset HSS was observed in a 36-year-old man presenting with progressive dysarthria. Markedly dysarthric speech and a weak atrophic tongue associated with a neurogenic pattern of motor unit recruitment in bulbar-supplied muscles on electromyography led to an initial impression of bulbar
amyotrophic lateral sclerosis
(
ALS
). Lack of expected progression of symptoms, however, prompted reinvestigation. Repeat brain magnetic resonance imaging demonstrated an "eye-of-the-tiger" pattern in the basal ganglia, characteristic of HSS, thus requiring genetic studies. DNA analyses of the
pantothenate kinase
gene (PANK2) was conducted and revealed two novel, disease-causing exon 3 missense mutations (Cys231Ser and Tyr251Cys). This case broadens the genotypic and phenotypic spectrum of HSS to include a late-onset syndrome resembling bulbar-onset
ALS
