UNASSIGNED: A 57-year-old with persistent right-sided headaches had a substantial hyperdense mass in the right middle cranial fossa, eroding petrous bone. Magnetic resonance imaging and digital subtraction angiography revealed a giant cavernous segment fusiform aneurysm of the right internal carotid artery (ICA) with spontaneous thrombosis and distal ICA occlusion. Collateral circulation maintains the cerebral blood supply. Despite anatomical challenges, conservative management was chosen due to the patient\'s stability.
UNASSIGNED: This case highlights the complex interplay between thrombosed giant aneurysms and affected vessels, with unique features such as cross-flow, calcification, and bone erosion. We advocate conservative management for stable cases, supported by literature, emphasizing vigilant follow-up. This expands the spectrum of aneurysm presentations and encourages further research into their dynamics.
■一名57岁的患有持续性右侧头痛的患者在右中颅窝有大量高密度肿块,侵蚀岩骨。磁共振成像和数字减影血管造影显示右颈内动脉(ICA)的巨大海绵样段梭形动脉瘤,伴有自发性血栓形成和远端ICA闭塞。侧支循环维持大脑血液供应。尽管面临解剖学挑战,由于患者的稳定性,选择了保守的管理。
■这个案例突出了血栓形成的巨大动脉瘤和受影响的血管之间复杂的相互作用,具有独特的功能,如交叉流动,钙化,骨侵蚀。对于稳定的案件,我们主张保守管理,在文学的支持下,强调警惕的后续行动。这扩展了动脉瘤表现的范围,并鼓励对其动力学的进一步研究。
