Opsoclônus-mioclônus (OM) é um transtorno autoimune dos movimentos oculares caracterizado por opsoclônus (movimentos oculares rápidos [sacádicos] involuntários e imprevisíveis sem intervalos intersacádicos), mioclônus (breves contrações musculares involuntárias). Ataxia está frequentemente presente e, enquanto a RNM costuma ser normal, o líquor pode ser inflamatório. OM pode ser paraneoplásica, pós infecciosa ou autoimune idiopática. OM paraneoplásica em crianças se associa a neuroblastoma, enquanto em adultos os cânceres de mama e de pequenas células do pulmão são os mais comuns. Muitos não apresentam um autoanticorpo neural concomitante, mas uma exceção é o anticorpo anti-neuronal tipo 2 [ANNA-2 ou anti-Ri] que está associado aos cânceres de mama, pulmão e ginecológicos. | |||||||||||||||

Opsoclonus-myoclonus (OM) is an autoimmune disorder of eye movements characterised by opsoclonus (involuntary unpredictable rapid eye movements [saccades] without inter-saccadic intervals), myoclonus (brief involuntary twitches). Ataxia is often present and while MRI is usually normal, spinal fluid may be inflammatory. OM may be paraneoplastic, post-infectious or idiopathic autoimmune. Paraneoplastic OM in children associates with neuroblastoma, while in adults breast and small-cell-lung cancers are most common. Most do not have an accompanying neural autoantibody, but an exception is the anti-neuronal nuclear antibody type 2 [ANNA-2 or anti-Ri] which is associated with breast, lung and gynaecological cancers. | |||||||||||||||
