颅内少见类型动脉瘤的病理、影像和治疗

Pathology, imaging and treatment of rare types of intracranial aneurysms

颅内少见类型动脉瘤形成机制各异,从而导致其治疗方法不同.本文通过文献回顾对颅内少见类型动脉瘤包括节段性扩张性动脉瘤、夹层动脉瘤、动脉瘤壁内血栓性动脉瘤、霉菌性动脉瘤、HIV相关性动脉瘤、肿瘤性动脉瘤、创伤性动脉瘤的发病原因及血管壁病理改变、影像特征进行总结,期望对动脉瘤的治疗有所帮助.

The formation mechanisms of rare intracranial aneurysms are various,which lead to various kinds of treatment methods.The present article summarized the pathogenesis,pathologic changes in vascular walls and imaging features of rare intracranial aneurysms including segmental ectasia,aneurysms with dissection,aneurysms with intramural hemorrhage,mycotic aneurysms,aneurysms related to HIV,neoplastic aneurysms and traumatic aneurysms through literature review.
