Oculomotor nerve schwannoma associated with ophthalmoplegic migraine
1Midwest Eye Institute, Clarian Hospitals of Indiana, Department of Ophthalmology and Neurology, Indiana University Medical Center, Indianapolis, USA.
Purpose:
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.
