ABSTRACT
The perivascular space is formed by the pia mater around the blood vessels and participates in the fluid exchange and waste clearance in the brain. The enlarged perivascular space (EPVS) indicates the disorder of brain clearance mechanism, which is closely related to the occurrence and development of a variety of clinical diseases. In recent years, there are a lot of studies on the pathogenesis and influencing factors of EPVS. This article reviews its anatomy, neuroimaging, pathogenesis, and risk factors.
