Ophthalmoplegic migraine.

A 5-year-old girl developed severe periocular pain lasting 4 days. As the pain subsided, a right oculomotor palsy developed which slowly resolved without aberrant regeneration over a 2 1/2-month period. A classic history and normal high-resolution CT scan were essential in making the diagnosis of ophthalmoplegic migraine. This is a rare disorder classically requiring normal cerebral angiography for diagnosis. With the advent of high-resolution CT scanning, angiography may no longer be indicated in the typical case.
