Although spontaneous cervical artery dissection (CAD) is an uncommon cause of stroke in the general population, it accounts for 10–25% of cerebrovascular events in young to middle-aged patients. Two or more vessels are involved in fewer than 15% of dissections, but multiple spontaneous CADs are likely to be underestimated owing to frequent spontaneous recanalization and the possible oligo-symptomatic presentation. An extensive review of the literature shows that in the last 30 years only 28 cases of multiple CADs have been reported, and that in half of these patients symptoms were minor and transient. We describe two cases of multiple spontaneous CADs presenting as transient ischemic attack (TIA), in which only a specific diagnostic flow-chart allowed us to recognize multiple vessel involvement and start the appropriate therapy.
