TO THE READERSHIP: A clarification is needed in the article by Goyal et al. (Goyal A, Yolcu YU, Goyal A, et al. The T2-FLAIR–mismatch sign as an imaging biomarker for IDH and 1p/19q status in diffuse low-grade gliomas: a systematic review with a Bayesian approach to evaluation of diagnostic test performance. Neurosurg Focus. 2019;47[6]:E13).

The Conclusions section in the abstract and text states that the T2-FLAIR–mismatch sign is a highly specific marker of IDH mutation but not 1p/19 codeletion in diffuse low-grade gliomas, although there may be exceptions to this finding. To avoid confusion to the readership, we would like to amend it to read as follows: “The T2-FLAIR–mismatch sign was an insensitive but highly specific marker of IDH mutation and IDHmut-Noncodel profile, although significant exceptions may exist to this finding. Tumors with a positive sign may still be IDHwt or 1p/19q codeleted.”

The article has been corrected online as of May 1, 2020.
