The “Blast” Behind Jerky Eyes

Abstract Opsoclonus is defined as hyperkinetic, omnidirectional, spontaneous, and involuntary chaotic eye movements. Opsoclonus-myoclonus-ataxia syndrome is addressed by many names including “dancing eyes-dancing feet syndrome,” “Kinsbourne syndrome,” and “infantile polymyoclonia.” The early accounts of the clinical syndrome date back to 1962 when Marcel Kinsbourne described six cases of this phenotype. However, it was not until 1968 the association with occult neuroblastoma was first reported. We report the video of a 1-year-old boy who presented with this syndrome for a duration of 3 months. He was diagnosed to have an abdominal neuroblastoma and was treated with resection of the tumor and administration of intramuscular adrenocorticotropic hormone. He showed complete resolution of symptoms. The syndrome is difficult to recognize and might be confused with seizures, tremors, or chorea; hence, it is important that residents learnt to recognize this syndrome and look for an underlying tumor actively.
