Abstract

Background: Dural sinus arteriovenous malformation is an uncommon intracranial vascular malformation. The affected cases may suffer from severe neurological injury. Prenatal ultrasound has been used to diagnose fetal intracranial vascular abnormality, but prenatal three-dimensional (3D) ultrasound presents a very rare anomaly; an arteriovenous malformation of the dural sinus has not been reported.

Objective: This study aimed to emphasize the diagnostic value of 3D ultrasound in the fetus with dural sinus arteriovenous malformation.

Case presentation: A 38-year-old woman was referred for targeted fetal ultrasonography at 37 weeks of gestation due to an ultrasound that showed a cystic lesion in the posterior cranial fossa. The fetus demonstrated obvious dilatation of the torcular herophili, bilateral transverse sinuses, and bilateral sigmoid sinuses, appearing as a novel bull's horn sign on 3D ultrasound. After birth, cerebral angiography confirmed the diagnosis of dural arteriovenous fistula (DAVF) in the occipital sinus region.

Conclusion: 3D ultrasound is an appealing method for prenatal diagnosis of dural sinus arteriovenous malformation.

硬脑膜窦动静脉畸形的产前三维超声诊断：一个不寻常的病例报告

背景：硬膜窦动静脉畸形是一种不常见的颅内血管畸形。受影响的病例可能会遭受严重的神经损伤。产前超声已被用于诊断胎儿颅内血管畸形，但产前三维（3D）超声显示的异常非常罕见；硬脑膜窦动静脉畸形尚未见报道：本研究旨在强调三维超声对硬脑膜窦动静脉畸形胎儿的诊断价值：一名 38 岁女性在妊娠 37 周时因超声检查显示后颅窝有囊性病变而转诊进行胎儿超声定向检查。胎儿的蝶窦、双侧横窦和双侧乙状窦明显扩张，在三维超声上表现为新颖的牛角征。结论：三维超声是产前诊断硬脑膜窦动静脉畸形的有效方法。
