[Opsomyoclonus syndrome in children. A new case. Review of the literature (110 cases)].

The authors report a new case of infantile myoclonic encephalopathy with opsoclonus and neuroblastoma in a 14 months-old infant. Some immunologic abnormalities were found at the initial course of the disease. The review of 110 cases of "dancing-eyes syndrome" permit them to specify clinical features and prognosis but cannot explain the pathogenesis of this rare disease.
