Facial diplegia complicating a bilateral interval carotid artery dissection

Background and Purpose-We report a case of facial diplegia complicating a b ilateral internal carotid artery dissection. Case Description-A 49-year-old patient presented with unilateral headache a nd oculosympathetic paresis. Cerebral angiography revealed a bilateral inte rnal carotid artery dissection. A few days later, the patient developed a f acial dipIegia that regressed after arterial recanalization. An arterial an atomic variation may explain this ischemic complication of carotid dissecti on. Conclusions-Double carotid dissection should be included among the causes o f bilateral seventh nerve palsy.
