The arachnoid membranes are projections of connective tissue in the subarachnoid space that connect the arachnoid mater to the pia mater. These are underappreciated and largely unrecognized by most neuroradiologists despite being found to be increasingly important in the pathogenesis, imaging, and treatment of communicating hydrocephalus. This review aims to provide neuroradiologists with an overview of the history, embryology, histology, anatomy, and normal imaging appearance of these membranes, as well as some examples of their clinical importance.
蛛网膜是蛛网膜下腔中的结缔组织突起，将蛛网膜与软膜相连。尽管在交通性脑积水的发病机制、影像学和治疗中越来越重要，但这些膜被大多数神经放射科医生低估和广泛忽视。本综述旨在为神经放射科医生提供这些膜的历史、胚胎学、组织学、解剖学和正常影像学表现的概述，以及它们在临床上的重要性的一些例子。
