Ophthalmoplegic migraine.

Ophthalmoplegic migraine is a rare condition usually beginning in infancy or childhood and characterized by paralysis of ocular cranial nerves in association with vascular headache. The diagnosis is one of exclusion. Most patients should have high resolution magnetic resonance imaging (MRI) or magnetic resonance angiography (MRA) to eliminate the possibility of aneurysm, tumor, or granulomatous inflammation.
