Ophthalmoplegic migraine with trigeminal nerve involvement.

We report a 25-year-old man with a history of uncontrolled migrainous headaches who developed third nerve palsy and sensory loss over V1 distribution of trigeminal nerve, during an attack of severe migraine. Gadolinium-enhanced MRI of the brain and cavernous sinus was normal and did not disclose nerve enhancement. CT angiogram was also normal. The patient recovered uneventfully in 2 weeks on oral steroids. The commonest cranial nerve implicated in ophthalmoplegic migraine is the occulomotor nerve. Involvement of the fifth nerve has never been reported.
