Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological condition involving diverse neurological manifestations as headaches, altered mental status, seizures, and visual disturbances.1 Characteristic imaging findings of reversible vasogenic brain oedema are reportedly observed not only in the occipital lobe but also in every other part of the brain.3 PRES is associated with many clinical factors including hypertension, chronic kidney disease (CKD), infection, immunosuppression, autoimmune disease, post‐transplantation status, and preeclampsia/eclampsia.1 The pathophysiology of PRES remains controversial. Treatment for PRES focuses on controlling general conditions, such as antihypertensive therapy and removal of precipitating factors. Reports of patients with PRES have been accumulating, but relatively few cases of PRES triggered by CKD and infection have been reported.5 We describe three cases of PRES triggered by CKD and infection.
