Multicenter cohort reveals imaging phenotype impacts treatment outcomes in sacral dural tears related to SIH, suggesting a distinct subtype.
Epidural patching outcomes in sacral dural tears causing SIH are driven primarily by baseline imaging phenotype, disease stage, and intracranial imaging response rather than procedural technique. These findings support a morphology- and chronicity-aware approach to diagnosis and treatment and suggest that sacral dural tears represent a distinct SIH subtype with outcome patterns similar to other leak mechanisms.
