Dear Editor,

Today, I have received the statement of Prof. Schumacher from our Department of Neuroradiology which is addressing our publication Schubert et al. 2009, 25:1419–1427 in your journal Child’s Nervous System. In his statement, Prof. Schumacher raises concerns about the use of data and images in this publication not being intellectual and material property of the authors. We declare that we did use neuroradiological images that were performed in the Department of Neuroradiology for retrospective analysis. As an act of courtesy, this could have also been mentioned in the Acknowledgments and I apologize for the irritations this has caused. I have agreed to settle this issue in this way.
