title: [Opsoclonus-myoclonus syndrome in children with neuroblastoma: description of 3 cases].
abstract: Neuroblastoma (NBL) is one of the most common childhood malignancies. Presence of untypical symptoms is characteristic for this malignancy; therefore it may mimic many other illnesses, both malignant and nonmalignant. Particular attention should be focused on opsoclonus-myoclonus syndrome (OMS, Kinsbourne's syndrome). In this paper three children with NBL previously diagnosed with OMS are presented. There is a need to test children with OMS for NBL as more than 30% of them are diagnosed with a tumor of neural origin. Children with NBL suffering from OMS have usually a favorable outcome with respect to their malignancy. However, the neurological and cognitive deficits are present for a long time and even they may become more intensive in spite of immunosuppressive therapy.
