We report a 19-year old woman with a choroidal-type vein of Galen aneurysmal malformation who presented with hydrocephalus. This venous malformation was fed by multiple fistulas and drained into the superior sagittal sinus through a persistent falcine sinus (precursor of the straight sinus). The hydrocephalus was treated by ventriculoperitioneal shunting, and the patient remained well for 9 years. At this time, magnetic resonance imaging (MRI) and magnetic resonance angiography demonstrated a vein of Galen aneurysmal malformation in the right thalamus, with a Chiari I appearance. This case may provide valuable data regarding the natural history of such venous malformations.
我们报告了一名19岁患有脉络丛型大脑大静脉动脉瘤样畸形并伴有脑积水的女性患者。这种静脉畸形由多个瘘口供血，并通过一条持续存在的镰状窦（直窦的前身）引流至上矢状窦。脑积水通过脑室腹腔分流术进行治疗，患者9年来情况良好。此时，磁共振成像（MRI）和磁共振血管造影显示右侧丘脑存在大脑大静脉动脉瘤样畸形，呈Chiari I型表现。该病例可能为此类静脉畸形的自然病史提供有价值的数据。
