Bilateral vertebral artery dissection - Multiple artery affection or early recurrence?

In a certain percentage of patients with craniocervical artery dissection, dissections aff ect multiple arteries. Some investigators consider that the dissections diagnosed as multiple might have occurred sequentially within a short time frame. We describe an oligosymptomatic patient with bilateral progressive vertebral artery dissection. Careful history taking added new data on transient left arm weakens two months earlier, as a possibility of the earlier disease onset.
