Migraine Headaches (MH) are the 6th leading cause of years lived with disability worldwide, affect 15% of the US population, and are nearly twice as prevalent in veterans who have been deployed. Our study focuses on pathology of the greater occipital nerve (GON), which occurs with a high prevalence in individuals with a history of trauma (i.e. traffic accidents, explosions, falls). In our pilot MRI scans and operative experience, migraines associated with GON pathology displayed a pathologic thickening of the nerve validated intraoperatively. These results present MRI as a potential biomarker of headache pathologies of MH associated with GON pathology.
