The finding of dilated, elongated, and tortuous vessels on brain imaging should prompt clinicians to determine what vascular anomaly is present. Importantly, not all suspicious serpentine flow voids are manifestations of arteriovenous malformations or arteriovenous fistulas. Other types of intracranial vasculopathies should also be considered. The authors report a rare case of dilated, tortuous, and redundant left posterior communicating artery and left P2 segment of the posterior cerebral artery identified in a young healthy adult that remained stable over a 30-year period. Dynamic and 3D images were critical for determining the type of vascular anomaly and for guiding appropriate management. The authors propose that this case represents a pure arterial malformation and discuss its distinguishing features.
在脑部影像学检查中发现扩张、延长和扭曲的血管时，临床医生应确定存在哪种血管异常。重要的是，并非所有可疑的蛇形流空信号都是动静脉畸形或动静脉瘘的表现。还应考虑其他类型的颅内血管病变。作者报告了一例罕见的病例，一名年轻健康的成年人在 30 年的时间里，左侧后交通动脉和大脑后动脉 P2 段均存在扩张、扭曲和冗余，影像学表现为扩张、延长和扭曲的血管。动态和 3D 图像对于确定血管异常的类型和指导适当的治疗至关重要。作者提出该病例代表一种单纯的动脉畸形，并讨论了其特征。
