Opsoclonus-Myoclonus Syndrome Post-Vaccination and Viral Illness

Opsoclonus-myoclonus syndrome is a rare condition with dyskinesia of eye movements and myoclonic movements of the trunk and limbs. It is linked to malignancies, infections and other conditions. We present a case of post-vaccination opsoclonus-myoclonus syndrome. We believe that our patient also experienced a viral illness post-vaccination and prior to the development of opsoclonus-myoclonus. The vaccination in combination with the viral illness potentiated the immune mechanism thought to be noted in this condition. This was supported by her recovery after receiving immunotherapy.
