Abstract

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological syndrome, characterized by

acute onset of headache, altered mental status, visual impairment, nausea, vomiting, seizure, and hypertension.

PRES is a reversible condition if it is recognized early, but neurological damage or even death may occur. Herein,

we present two cases of ALL who developed PRES during their induction therapy and a literature review of PRES.
