Bilateral Cervical Carotid and Intracranial Vasospasm Causing Cerebral Ischemia in a Migrainous Patient: A Case of "Diplegic Migraine"




A patient with a 15-year history of migraine exhibited the rapid onset of bilateral cerebral ischemia associated with bilateral cervical carotid and intracranial focal arterial narrowing (vasospasm). The neurological signs and symptoms and angiographic findings resolved spontaneously within a few days. Among the rarely documented cases of vasospasm in migrainous subjects, this illustrates the bilaterality of ischemic symptoms and the unusual involvement of both extracranial carotid arteries.
