Brain arteriovenous malformations (AVM) are treated with endovascular embolization either as a definitive treatment or as an adjunct to surgery or stereotactic radiotherapy. Complications of AVM embolization are well known but infection of the embolised AVM nidus is extremely rare. On Pubmed search we found only a single case report of an infected brain AVM after embolization. We report a case of pyogenic cerebral abscess with superior sagittal sinus extension complicating an embolised AVM and discuss the possible etiopathogenesis.
脑动静脉畸形（AVM）可通过血管内栓塞治疗，作为一种确定性治疗方法，或作为手术或立体定向放射治疗的辅助手段。AVM栓塞的并发症是众所周知的，但栓塞的AVM病灶感染极为罕见。在PubMed搜索中，我们仅发现一篇关于栓塞后脑AVM感染的病例报告。我们报告一例化脓性脑脓肿伴上矢状窦扩展，使栓塞后的AVM复杂化，并讨论可能的病因。
