Association between renal insufficiency and lesion characteristics of posterior reversible encephalopathy syndrome.

Background: Posterior reversible encephalopathy syndrome (PRES) is characterized by cerebral blood flow dysregulation and the blood-brain barrier (BBB) disruption. While renal insufficiency has been considered a factor in BBB fragility, the relationship between renal insufficiency and the PRES lesions volume remains unclear.

Methods: This observational study was performed retrospectively.
