[Generalized myoclonus as the only symptom of neurosyphilis]

Symptomatic myoclonus syndromes can be caused by a broad range of etiological factors. We report the case of a 40-year-old woman who showed spontaneous and continuous myoclonus with predominance distally and in the arms as the only neurological symptom. CSF evaluation revealed acute neurosyphilis. Six months after antibiotic treatment, the movement disorder had disappeared.
