    Newly Recognized Genetic Tumor Syndromes of the CNS in the 5th WHO Classification: Imaging Overview with Genetic Updates

    American Journal of Neuroradiology February 2024, 45 (2) 128-138; DOI: https://doi.org/10.3174/ajnr.A8039

    In this review of the new 5th edition of the WHO classification, the authors focus on imaging and genetic characteristics of 8 new syndromes: Elongator protein complex-medulloblastoma syndrome, BRCA1-associated protein 1 tumor-predisposition syndrome, DICER1 syndrome, familial paraganglioma syndrome, melanoma-astrocytoma syndrome, Carney complex, Fanconi anemia, and familial retinoblastoma.

    Quantification of T2-FLAIR Mismatch in Nonenhancing Diffuse Gliomas Using Digital Subtraction

    American Journal of Neuroradiology February 2024, 45 (2) 188-197; DOI: https://doi.org/10.3174/ajnr.A8094

    The T2-FLAIR mismatch sign on MR imaging, usually determined by visual assessment, is a highly specific imaging biomarker of IDH-mutant astrocytomas. The authors of this study quantified the degree of T2-FLAIR mismatch in nonenhancing diffuse gliomas. Thresholds of ≥42% T2-FLAIR mismatch volume classified IDH-mutant astrocytoma with a specificity/sensitivity of 100%/19.6% (TCIA) and 100%/31.6% (institutional). They also found that grades 3–4 compared with grade 2 IDH-mutant astrocytomas (P<.05) had a higher percentage T2-FLAIR mismatch volume.

    Radiogenomics Provides Insights into Gliomas Demonstrating Single-Arm 1p or 19q Deletion
    Arian Lasocki, Michael E. Buckland, Tahlia Molinaro, Jing Xie and Frank Gaillard
    American Journal of Neuroradiology November 2023, 44 (11) 1270-1274; DOI: https://doi.org/10.3174/ajnr.A8034

    The results of this study show that imaging and survival data of tumors with single-arm 1p or 19q deletion are equivalent to IDH-mutant astrocytomas rather than oligodendrogliomas. Not only does this support our understanding of the neurobiologic underpinnings, but it also provides reassurance in the management of these tumors with 1p- or 19q-unideletion as astrocytomas, in keeping with the WHO classification.
