[Painful ophthalmoplegia in children: Tolosa-Hunt syndrome or ophthalmoplegic migraine?].

In children with painful ophthalmoplegia, the diagnosis of Tolosa-Hunt syndrome or of ophthalmoplegic migraine should only be considered when tumoral, infectious, inflammatory or vascular causes have been excluded by appropriate investigations. Both entities are classified as "neuralgia" by the International Headache Society, and seem to share a similar pathogenic mechanism. Both diseases have many clinical similarities with slight differences concerning pain characteristics or ocular associated symptoms. High resolution CT scan or contrast enhanced MRI can be necessary to exclude other causes of painful ophthalmoplegia. They can sometimes objectify an inflammatory process of the cavernous sinus in Tolosa-Hunt syndrome or a reversible enhancement and thickening of the cisternal segment of the oculomotor nerve during an ophthalmoplegic migraine. Pain and ophthalmoplegia quickly resolve with corticosteroids. Such treatment may decrease the risk of recurrence. It is important to follow-up these patients for a 2 years period and to repeat the etiologic assessment. We report here 2 cases of children with painful ophtalmoplegia.
