Tourettism as clinical presentation of Huntington's disease with onset in childhood.
Infantile Huntington's disease (HD) shows a wide clinical heterogeneity. Here we describe the case of a child affected by HD who showed unusual neurological features consistent with tourettism. The absence of family history and persisting normal magnetic resonance imaging (MRI) results long after the onset of symptoms delayed the diagnosis of the disease. An MRI exam performed 26 months after disease onset disclosed bilateral atrophy in the putamen, suggesting HD. The diagnosis was confirmed by genetic analysis. The present report underlines the need to consider HD in childhood cases of unusual and even unfamiliar progressive movement disorders.
