Paroxysmal dystonia and neuromyelitis optica Distonia paroxística e neuromielite óptica

Paroxysmal dyskinesias (PD) are thought to be rare movement disorders. The overwhelming majority of reported cases are primary. Secondary PD has seen reported to occur in some conditions, mainly in multiple sclerosis and head trauma. The anatomic origin of the lesion is also rarely seen at the spinal cord. Our objective was to describe four patients with paroxysmal dystonia secondary to spinal lesions during the recovering phase of a neuromyelitis optica (NMO) bout. In the reviewed literature, we do not find any report of PD related to NMO.Discinesias paroxísticas (DP) são distúrbios do movimento raros. A maioria dos casos relatados é de origem primária. DP secundárias têm sido relatadas em algumas condições, principalmente na esclerose múltipla e no trauma craniano. A origem anatômica da lesão também é raramente observada na medula. O objetivo deste trabalho foi descrever quatro pacientes com distonia paroxística secundária a lesões medulares, ocorrida durante a fase de recuperação do surto de neuromielite óptica (NMO). Na literatura consultada, não encontramos qualquer relato de DP secundárias à NMO
