The widespread use of MR has led to the increasingly frequent diagnosis of unruptured incidental intracranial aneurysms. Most are small (<7 mm diameter) and will never rupture. Yet, their recognition causes much anxiety, and their optimal management remains controversial. This review addresses the difficulties in managing incidental unruptured saccular intracranial aneurysms. Note that our conclusions and recommendations do not apply to symptomatic unruptured aneurysms or to fusiform, dissecting, mycotic, traumatic and paediatric aneurysms, each of which has a different natural history.

意外未破裂颅内动脉瘤的处理

MR 的广泛使用导致未破裂的偶然颅内动脉瘤的诊断越来越频繁。大多数都很小（<7 毫米直径）并且永远不会破裂。然而，他们的认可引起了很多焦虑，他们的最佳管理仍然存在争议。本综述讨论了处理偶发未破裂囊状颅内动脉瘤的困难。请注意，我们的结论和建议不适用于有症状的未破裂动脉瘤或梭形动脉瘤、夹层动脉瘤、真菌性动脉瘤、创伤性动脉瘤和小儿动脉瘤，它们都有不同的自然病程。
