Oculomotor nerve schwannoma associated with ophthalmoplegic migraine.
OBJECTIVE
To describe a patient with an oculomotor nerve schwannoma who had symptoms of ophthalmoplegic migraine.


METHODS
Case report.


RESULTS
A 23-year-old woman had a history of recurrent headache accompanied by transient right oculomotor palsy since age 7 years. Ophthalmoplegic migraine was diagnosed. She was subsequently found to have a structural lesion of her right oculomotor nerve on magnetic resonance imaging. The magnetic resonance image characteristics were consistent with schwannoma originating from the oculomotor nerve.


CONCLUSIONS
This case illustrates that an intrinsic lesion of the oculomotor nerve (schwannoma) may be associated with a painful relapsing-remitting oculomotor palsy mimicking the clinical syndrome of ophthalmoplegic migraine.
