Posterior Reversible Encephalopathy Syndrome in children/ adolescents with hematologic malignancies: Case reports

Abstract

INTRODUCTION: Posterior Reversible Encephalopathy Syndrome (PRES) is one of the most common neurological complications in pediatric onco-hematology. Hematologic malignancies and cytotoxic chemotherapy are involved in its pathogenesis. It's a clinical and radiological entity: the diagnosis of PRES is based on both clinical symptoms and neuroimaging data. OBSERVATION: Here we reported a series of four cases of children/ adolescents treated by cytotoxic chemotherapy for hematologic malignancies who developed neurologic disorders and their magnetic resonance imaging findings were in favor of PRES. CONCLUSION: In onco-hematology, children/ adolescents who present with new seizures, visual deficits, or other neurologic signs, PRES should be considered as a part of the differential diagnosis as a good outcome relies on rapid management of this complication.
