An 11-month-old female presented to the emergency department with a 2-week history of fever, increasing fussiness, emesis, and decreased urine output. She was diagnosed with acute myelogenous leukemia. Systemic chemotherapy with intensified intrathecal cytarabine was started, and the patient achieved a clinical remission after the first course of induction. Towards the end of her second course of induction she developed pseudohypopyon in each eye on consecutive days, heralding a central nervous system relapse.
