摘要

在24个月以下的婴儿中，突出的蛛网膜下腔（SAS）是一种非常常见的发现，是一种可能与大头畸形相关的正常变异。这必须与其他引起SAS的病理情况相区分，包括脑容量减少、脑脊液阻塞或颅骨畸形。一些作者团体不恰当地将正常SAS突出标记为病理所致的增大，以及对已发表文献的错误表述，在医学上造成了混淆，从而得出了不恰当的结论，即正常突出的SAS可能导致硬膜下出血（SDH）和脑损伤。本文旨在回顾婴儿SAS的特征，与SAS突出相关的术语以及SAS突出与SDH之间可能的联系。

The Prominent Subarachnoid Space in Children: How has a Normal Variant Become Medicolegally Life-Threatening Pathology?

A prominent subarachnoid space (SAS) in infants under 24 months is a very common finding and is a normal variant that can be associated with macrocephaly. This must be differentiated from various pathological conditions that also cause a prominent SAS, including a reduction in brain volume, obstruction to the cerebrospinal fluid (CSF) or malformations of the skull. The inappropriate labelling of normal SAS prominence as enlargement due to pathology and misrepresentation of published literature by some author groups has created confusion medicolegally, contributing to inappropriate conclusions that a normal prominent SAS may cause subdural haemorrhage (SDH) and brain injury. This paper aims to review the characteristics of the SAS in infants, the terminology relating to the prominence of the SAS and the possible association between the prominence of the SAS and SDH.
