Parkisonism induced by high‐dose cytosine arabinoside

Abstract
We report a severe parkinsonian condition following high dose, parenteral cytosine arabinoside (Cytosar) that persisted for 8 weeks. The durg was used in a patient with acute myelogenous leukemia that was refractory to all other treatment. The syndrome was partially responsive to antiparkinsonian durgs and fortunately remitted completely within 12 weeks.
