Abstract
Posterior reversible encephalopathy syndrome (PRES) was first codified as a single named syndrome in a 1996 case series by Hinchey et al. PRES was described as a clinical syndrome of insidious onset of headache, confusion, visual changes and seizures, which was associated with neuroimaging findings of posterior cerebral white matter edema. Hypertensive disorders, renal disease and immunosuppressive therapies so on are risk factors for this disorder. There are few reports of PRES caused by hypercalcemia. We report herein on a rare case of PRES in normotensive patient with hypercalcemia as a complication of an endstage oral cancer.
