Background: Oculomotor ophthalmoplegic migraine (O-OPM) occurs in many children, and in some cases MRI shows a small mass in the root exit zone (REZ) of the oculomotor nerve. This mass is considered to result from nerve hypertrophy caused by repeated demyelination.Case results: A 51-year-old man has been on oral medication for O-OPM, which he had from 6 years of age. However, the frequency and intensity of his migraine attacks have gradually increased. Brain magnetic resonance imaging (MRI) revealed a small nodular mass in the REZ of the oculomotor nerve. The mass was initially diagnosed as oculomotor schwannoma and tumor resection was attempted. However, as the mass was tightly adhered to the oculomotor nerve and hemorrhagic, biopsy was performed. The pathological diagnosis was neuromuscular hamartoma.Conclusion: The small nodular mass in the REZ of the oculomotor nerve may be a hamartoma associated with congenital factors and may possibly be the primary pathology of O-OPM in this case. |
