Aneurysmal dilatation of the vein of Galen (AVG) is a common finding in vascular malformations that involve the Galenic system and spontaneous thrombosis is very rare. Although the presentation of the cases may differ with the age, the mortality and morbidity is high in all age groups. Here, we present a case of AVG in a six-month-old boy. The patient underwent insertion of a ventriculoperitoneal shunt. Surveillance of the lesion with subsequent MRI revealed spontaneous thrombosis of the AVG with excellent clinical outcome. Proposed mechanisms of spontaneous thrombosis include slow flow shunts, obstruction of the venous outflow or obstruction of the feeding artery. The case is discussed with the relevant literature.
大脑大静脉瘤样扩张（AVG）是累及大脑大静脉系统的血管畸形中的常见表现，自发性血栓形成非常罕见。尽管病例表现可能因年龄而异，但所有年龄组的死亡率和发病率都很高。在此，我们报告一例6个月大男孩的AVG病例。该患者接受了脑室腹腔分流术。随后通过MRI对病变进行监测，发现AVG出现自发性血栓形成，临床结局良好。自发性血栓形成的推测机制包括缓慢血流分流、静脉流出道阻塞或供血动脉阻塞。本文结合相关文献对该病例进行了讨论。
