The subcutaneous CSF reservoirs (Ommaya reservoir) were used for the prevention of CNS leukemia in two children with ALL during second remission. Cranial irradiation was already performed during first remission. Epidural hematoma beneath the reservoir and communicating hydrocephalus occurred during remission induction therapy for second bone marrow relapse. The CNS complications of Ommaya reservoir were summarized and the indications of the reservoir in childhood ALL were discussed.
