WebJan 30, 2024 · CSF has not been recognized as a source of edema fluid, but the notion that perivascular spaces (PVS) provide a conduit for CSF influx prompted us to reassess this idea. Glymphatic exchange of CSF with the interstitial fluid provides a means by which CSF in large quantities may rapidly enter the brain and drive tissue swelling( 23 , 24 ).
