Ophthalmoplegic migraine in a child, an accelerated clinical and radiologic response to steroid therapy

ABSTRACT

Ophthalmoplegic migraine is characterized by recurrent attacks of migraine-like headache with paresis of ocular cranial nerves. To date, the exact etiology of ophthalmoplegic migraine remains unknown. We report a 9-year-old girl with typical clinical features of ophthalmoplegic migraine. She presented to us shortly after onset of her fi fth episode. The initial episodes of opthalmoplegia used to last for about 2-3 months with gradual and complete recovery. Brain MRI with contrast study revealed a thickened, enhancing right oculomotor nerve in the cisternal segment during the acute phase of ophthalmoplegia. She was treated with steroid for two weeks as well as with divalproex sodium for prophylaxis of migraine. There was complete recovery of ophthalmoplegia after four weeks of treatment with complete resolution of third nerve enhancement on repeat imaging. There were no further episodes of ophthalmoplegia within a follow up period of one year. Steroid therapy may hasten the recovery of ophthalmoplegia and prophylactic treatment of migraine may reduce the episodes and severity of ophthalmoplegic migraine.
