Swelling of the third nerve in a child with transient oculomotor paresis : A possible cause of ophthalmoplegic migraine

Abstract Transient oculomotor nerve palsy is rarely observed in childhood and mostly is recognized to be a migraine equivalent. We report an 8-year old girl who presented with recurrent attacks of transient oculomotor paresis. The clinical profile of the patient suggested transient dysfunction in the context of an ophthalmoplegic migraine. A CT scan was normal, but MRI demonstrated a swollen right oculomotor nerve.
