passages.text: A 7-year-old girl with an unusual reaction to induction chemotherapy for precursor B-cell acute lymphoblastic leukemia (ALL) is described. The patient developed acute encephalopathy evidenced by behavioral changes, aphasia, incontinence, visual hallucinations, and right-sided weakness with diffuse cerebral vasospasm on magnetic resonance angiography after the administration of intrathecal cytarabine. Vincristine, dexamethasone, and polyethylene glycol-asparaginase were also administered before the episode as part of induction therapy. Neurologic status returned to baseline within 10 days of the acute event, and magnetic resonance angiography findings returned to normal 4 months later.
