Posterior reversible encephalopathy syndrome: a noteworthy syndrome in end-stage renal disease patients.

Background: Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiologic entity characterized by headache, visual disturbances, seizures, and the presence of edema on MRI scan, predominantly in the posterior white matter. Regarding end-stage renal disease (ESRD) and PRES, only a few cases of children on peritoneal dialysis (PD) and adults on hemodialysis have been described in the literature.

Cases: We report 4 cases of adult patients on PD who presented with PRES, all of which were due to hypertension and inadequate management of fluid balance.
