The purpose of this pictorial essay is to describe the recommendations of the 2021 World Health Organization classification for adult-type and pediatric-type gliomas and to discuss the main modifications in relation to the previous (2016) classification, exemplified by imaging, histological, and molecular findings in nine patients followed at our institutions. In recent years, molecular biomarkers have gained importance in the diagnosis and classification of gliomas, mainly because they have been shown to correlate with the biological behavior and prognosis of such tumors. It is important for neuroradiologists to familiarize themselves with this new classification of central nervous system tumors, so that they can use this knowledge in evaluating and reporting the imaging examinations of patients with glioma.
这篇图文并茂的文章旨在描述2021年世界卫生组织对成人型和儿童型胶质瘤的分类建议，并讨论与之前（2016年）分类相比的主要修改内容，以我们机构随访的9例患者的影像学、组织学和分子学发现为例进行说明。近年来，分子生物标志物在胶质瘤的诊断和分类中变得越来越重要，主要是因为它们已被证明与这类肿瘤的生物学行为和预后相关。神经放射科医生熟悉中枢神经系统肿瘤的这种新分类很重要，这样他们就可以在评估和报告胶质瘤患者的影像学检查时运用这些知识。
