Status Epilepticus and Reversible Hemiplegia During Induction Chemotherapy in Acute Lymphoblastic Leukemia

Posterior reversible encephalopathy syndrome (PRES) is one of the major causes of neurologic impairment commonly presenting with seizures or headaches, mental alterations or visual disturbances usually associated with hypertension in those children. It is known to be a potentially reversible entity with typical neurologic findings corresponding MRI abnormalities including hyperintense lesions within occipital-parietal subcortical or deep white matter regions bilaterally. In here, we share significant clinical and MRI findings of PRES, which emerged in a 10 yearold girl, recently received chemotherapy protocol for acute lymphoblastic leukemia (ALL). We aimed to increase familiarity of clinicians to PRES especially during treatment of leukemia which can be confused with some other severe neurologic complications including stroke or hemorrhage for early and appropriate management in order to avoid neurological sequel.
