A patient with unusual angiographic changes of a dissecting aneurysm of the basilar artery is presented. Initial angiography and magnetic resonance imaging revealed a typical dissecting aneurysm. However, a follow-up study demonstrated a saccular aneurysmal dilatation of the proximal part of the dissection. The importance of the follow-up study, particularly in regard to the usefulness of magnetic resonance imaging and the pathogenesis of this change are discussed.
本文报告了一名基底动脉夹层动脉瘤血管造影表现异常的患者。初次血管造影和磁共振成像显示为典型的夹层动脉瘤。然而，一项随访研究显示夹层近端呈囊状动脉瘤样扩张。讨论了随访研究的重要性，特别是关于磁共振成像的实用性以及这种变化的发病机制。
