Pure artery malformation (PAM) is defined as a coil-like dilated and or overlapping appearance of arterial vessels in the absence of a venous component [1]. We report the case of a young adult who presented with a headache and was found to have a pure artery malformation of the bilateral superior cerebellar arteries (SCA), initially masquerading as a basilar tip aneurysm. Given the uncertainty in the diagnosis on noninvasive neuroimaging, a digital subtraction angiography (DSA) was pursued, confirming the diagnosis of PAM. The long-term significance of PAMs remains unknown, but diligent initial evaluation is necessary to rule out alternative diagnoses, especially in an acute setting.
纯动脉畸形（PAM）被定义为在没有静脉成分的情况下动脉血管呈盘绕状扩张和/或重叠的表现[1]。我们报告了一例年轻成人病例，该患者因头痛就诊，被发现双侧小脑上动脉（SCA）存在纯动脉畸形，最初表现为基底动脉尖动脉瘤。鉴于无创神经影像学诊断存在不确定性，遂进行了数字减影血管造影（DSA），确诊为PAM。PAM的长期意义尚不清楚，但进行细致的初始评估以排除其他诊断是必要的，尤其是在急性情况下。
