The meninges are an important connective tissue envelope investing the brain. Their function is to provide a protective coating to the brain and also participate in the formation of blood–brain barrier. Understanding their anatomy is fundamental to understanding the location and spread of pathologies in relation to the layers. It also provides an insight into the characteristics of such pathologies when imaging them. This review aims to describe the anatomy of the meninges, and to demonstrate the imaging findings of specific features.
