Thickening and Contrast Enhancement of Spinal Roots on MR Imaging in Guillain-Barré Syndrome: Thoughts on Pathologic Background

摘要

I read with interest the article by Zuccoli et al1 evaluating the MR imaging findings in 17 children affected by Guillain-Barré syndrome (GBS) or Miller Fisher syndrome. Fourteen patients demonstrated cauda equina enhancement, with predominant involvement of the anterior roots. Furthermore, isolated enhancement of the anterior spinal roots was observed in 3 patients. Given that the authors make no reference to the pathologic hallmark of such neuroimaging findings, I wish to comment on this question.
