A magnetic resonance imaging study was performed in three symptomatic members of two families with a diagnosis of acetazolamide-responsive familial paroxysmal ataxia. A selective atrophy of the cerebellar vermis, mostly of the anterior part, was demonstrated in the three cases. The first ample documentation of a neuroanatomical abnormality in this condition was achieved in this study.
