Cerebral arteriovenous malformations (AVMs) have been commonly regarded as congenital. However, this suspected origin has been challenged by reports of de novo cerebral AVM.
We have described a 25-year-old man without any known history of cerebrovascular disease, in whom cranial imaging demonstrated the de novo appearance of a pial AVM. Initial magnetic resonance imaging at 11 years of age had revealed the presence of a 2-cm parafalcine arachnoid cyst. Computed tomography and magnetic resonance imaging performed 14 years later showed a new cerebral AVM in the left frontal lobe, which was then confirmed angiographically.
The findings from our case report and from 9 similar reports challenge the traditional theory that AVMs constitute congenital lesions.
脑动静脉畸形（AVM）通常被认为是先天性的。然而，新出现的脑 AVM 的报告对这种可疑起源提出了挑战。
我们描述了一名 25 岁的男性，没有任何已知的脑血管疾病史，其颅部成像显示出脑皮层 AVM 的新出现。11 岁时的首次磁共振成像显示存在 2 厘米的大脑镰旁蛛网膜囊肿。14 年后进行的计算机断层扫描和磁共振成像显示左额叶出现新的脑 AVM，随后经血管造影证实。
我们的病例报告和 9 份类似报告的结果挑战了 AVM 构成先天性病变的传统理论。
