Spontaneous cerebrospinal fluid fistula classification

Schievink et al. identified 3 types of spinal Spontaneous cerebrospinal fluid fistula in this observational study: the dural tear, the meningeal diverticulum, and the CSF-venous fistula. These 3 types and the presence or absence of extradural CSF form the basis of a comprehensive classification system ¹⁾.
