Dear Editor,

Our previous article, “The clinical experience of medulloblastoma treatment and the significance of time sequence for development of leptomeningeal metastasis”, was published in Child Nervous System 2008 Dec; 24(12): 1463–1467. Some efforts, especially data analysis, were contributed by colleagues in our associated institution. The full title of the contributing institutions should be: “Chang Gung Memorial Hospital, Chang Gang University and Medical College”, and we would like to make this announcement for their efforts.

Best regards,
