Long-term Ergotamine Derivative Therapy for Migraine Associated with Pachymeningitis and Sixth Cranial Nerve Palsy

Abstract

Chronic use of ergotamine derivatives has been well described in the literature to cause retroperitoneal, pleural, pericardial and valvular fibrosis. While acute migraine treatment advances have resulted in a reduction of ergotamine derivatives prescribing, they are still considered appropriate for some patients. We report a case of diffuse pachymeningitis with symptomatic right sixth cranial nerve palsy who had a history of long-term Cafergot© suppository use. To the best of our knowledge, this is the first case to temporally associate ergotamine derivatives with pachymeningitis.
