Cervical artery dissection (CeAD) is the most common cause of ischemic stroke in young and middle-aged adults. Over the last decade, a relation between CeAD and fibromuscular dysplasia (FMD), an idiopathic, segmental, non-atherosclerotic and non-inflammatory arterial disease, has been suggested based on a number of epidemiologic observations, while preliminary data support the idea that the two conditions may share common biologic mechanisms. In this article, we review the literature on the relation between CeAD and FMD, focus on the potential pathogenetic mechanisms common to the two conditions, summarize clinical features, management and outcome, and provide support to the hypothesis that the coexistence of the two diseases in one individual might be conceptualized as a distinct non-atherosclerotic non-inflammatory arteriopathy.
