Haemorrhage is the most frequent revealing condition of brain arteriovenous malformations (bAVMs). We report a rare case of unruptured parietal bAVM revealed by spontaneous thrombosis of the main draining vein, responsible for a focal neurological deficit. The bAVM was embolized in emergency conditions; complete regression of the neurological symptoms was observed within five days after the embolization. Potential mechanisms of such spontaneous thrombosis of the bAVM's main drainage pathway as well as an exhaustive review of the literature concerning this rare revealing condition are presented and discussed.
出血是脑动静脉畸形（bAVM）最常见的首发症状。我们报告了一例罕见的未破裂顶叶bAVM病例，其由主要引流静脉的自发性血栓形成所致，导致了局灶性神经功能缺损。该bAVM在紧急情况下接受了栓塞治疗；栓塞术后五天内观察到神经症状完全消退。本文介绍并讨论了bAVM主要引流途径发生这种自发性血栓形成的潜在机制，以及有关这种罕见首发情况的文献综述。
