A primary or systemic @entity4065 is frequently suspected in @entity1 with spontaneous cerebral or cervical artery dissections. The authors report on two @entity1 with such dissections accompanied by @entity69093 , a previously unreported association, and propose a common @entity245 in these @entity1 . A 50-year-old @entity1 with @entity69093 developed @entity158 . Angiography studies revealed a spontaneous @entity3538 (ICA) dissection and an ipsilateral fusiform @entity438 . The ICA dissection was treated with @entity117 , and after 6 months a craniotomy was performed. The @entity439 was found to be fusiform; it involved the entire supraclinoid portion of the ICA, and was wrapped with @entity2708 . A 49-year-old @entity1 with a congenitally bicuspid aortic valve and @entity69093 developed @entity4048 . Magnetic resonance imaging and angiography demonstrated a @entity439 . A craniotomy was performed and the @entity439 was found to incorporate the posterior @entity5487 as well as a perforating artery: the lesion was wrapped @entity2708 . The tunica media of the arteries of the head and neck as well as the aortic valvular cusps are derived from neural crest cells, and @entity69093 has been associated with @entity5 of neural crest derivation. These associations indicate that a @entity6648 may be the underlying abnormality in these @entity1 .
