Successful treatment of disseminated relapsed medulloblastoma in an infant by primary radiotherapy.

An infant who experienced disseminated relapse of medulloblastoma while receiving chemotherapy is described. He was subsequently treated with radiation therapy. Seven and one-half years from diagnosis, he is currently disease-free and enjoys a relatively normal life. We emphasize the importance of considering radiation as one of the treatment modalities for young children with relapsed medulloblastoma.
