To present anatomic variants of the fetal brain and artifacts related to scanning techniques that could be misinterpreted as abnormalities on prenatal neurosonographic studies.
The findings were derived from fetal neurosonographic studies performed routinely from 16 to 36 weeks' gestation during the last 3 years, supervised by a sonologist specialized in neonatal cranial sonography.
The pitfalls were divided into three groups: brain parenchyma, ventricular system and choroid plexus. We provide images of these pseudolesions and clues to their differentiation from true brain pathology.
Knowledge of misleading images seen on fetal neurosonographic studies that could be misinterpreted as lesions is essential for the proper interpretation of these studies and will help avoid the use of more invasive diagnostic tests. To the best of our knowledge, the majority of the pitfalls presented here have only been described in neonates.
介绍胎儿脑部的解剖变异以及与扫描技术相关的伪像，这些在产前神经超声检查中可能被误判为异常。
研究结果源自过去3年中在超声专家监督下，于妊娠16至36周期间常规进行的胎儿神经超声检查。
这些陷阱分为三组：脑实质、脑室系统和脉络丛。我们提供了这些假病变的图像以及将它们与真正脑部病变区分开来的线索。
了解胎儿神经超声检查中可能被误判为病变的误导性图像，对于正确解读这些检查至关重要，有助于避免使用侵入性更强的诊断测试。据我们所知，此处呈现的大多数陷阱仅在新生儿中有所描述。
