The authors retract the article “Mystery Case: CSF-1R mutation is a cause of intracranial cerebral calcifications, cysts, and leukoencephalopathy” by X. Ayrignac et al., which appeared in the Resident & Fellow Section in volume 86, page e262, because 4 of the figures were previously published in another journal (European Neurology 2012;67:151–153).2 The earlier article was not cited and there were 3 common authors (Magnin, Berger, and Labauge) on the papers. In addition to the duplicate publication, 1 image attributed to the index case in this article was attributed to his mother in the earlier article and 3 images attributed to his mother in this article were attributed to the index case in the earlier article.

When asked for an explanation, the corresponding author, X. Ayrignac, replied that he was unaware of the earlier paper, but agreed to represent all authors in retracting the paper. Coauthors Lumbroso, Mouzat, and Carra responded that they agreed with the retraction and were also unaware of the earlier publication and thus had no explanation for the mix-up of the figures or duplication publication. Coauthor Magnin, one of the overlapping authors, agreed with the retraction and stated that he did not know how the mix-up of the figures occurred and that he missed catching it at the manuscript review. Coauthor Labauge (an overlapping author) also agreed to the retraction and stated to the corresponding author that when he submitted the earlier paper, he did not realize the figures were incorrectly attributed and did not remember the first paper when he revised the Ayrignac et al. paper. Coauthor Berger (an overlapping author) was not available for a written reply, but the corresponding author stated that this author had verbally agreed to the retraction. None of the authors could explain the mix-up of the figures or the duplicate publication.

The corresponding author, Ayrignac, admits that this publication is a duplicate publication and thus should not have been published even with the identification of a mutation in the CSF1R gene. With regard to the mix-up of the figures, Ayrignac believes there was a mistake in the previous paper and that the images published in Neurology were correctly attributed to the index case and his mother.
