With the advent of more effective chemotherapy an increasing incidence of central nervous system involvement in acute lymphocyte (ALL) and myelocytic leukemias (AML) and chronic myelocytic leukemia (CML) in blast crisis has become evident. Meningeal involvement in the chronic phase of CML is rare. We report two children whose initial presentation of Ph1 CML was in the central nervous system as documented by cytocentrifugation. Aggressive combination chemotherapy and cranial irradiation has resulted in prolonged survival without blastic transformation or further meningeal disease. An approach to children with CML is suggested.
