BACKGROUND
This study aims to describe the imaging characteristic of dural sinus malformation in 4 fetuses with different locations.
MATERIALS AND METHODS
We report a series of 4 fetuses with dural sinus malformation in Hubei Maternal and Children's Hospital from July 2013 to February 2016. All the mothers undertook the prenatal magnetic resonance (MRI) imaging because of the intracranial space-occupying lesions discovered by prenatal ultrasound.
RESULTS
Two of the 4 cases demonstrated typical MRI of dural sinus malformation with thrombosis in the vicinity of torcular herophili (also known as sinus confluence), whereas the other 2 cases showed lesions in the superior sagittal sinus and transverse sinus separately. Three pregnancies were terminated, whereas the other one was delivered in the local hospital.
CONCLUSIONS
Sonographer should realize the sign of dural sinus malformation. Atypical location of the dural sinus malformation, such as superior sagittal sinus and transverse sinus, should be paid special attention to. Further, prenatal MRI is necessary to identify the lesion.
背景
本研究旨在描述4例不同部位硬脑膜窦畸形胎儿的影像学特征。
材料与方法
我们报告了2013年7月至2016年2月在湖北省妇幼保健院的一系列4例硬脑膜窦畸形胎儿。所有母亲因产前超声发现颅内占位性病变而接受了产前磁共振成像（MRI）检查。
结果
4例中有2例表现为典型的硬脑膜窦畸形MRI，在窦汇（也称为窦融合）附近有血栓形成，而另外2例分别在上矢状窦和横窦出现病变。3例妊娠终止，另一例在当地医院分娩。
结论
超声检查人员应认识到硬脑膜窦畸形的征象。对于硬脑膜窦畸形的非典型部位，如上矢状窦和横窦应予以特别关注。此外，产前MRI对于识别病变是必要的。
