Chordoid glioma (CG) is a rare brain tumor that is known for its characteristic location in the third ventricle. A wide spectrum of radiological presentations has been described, with few common features among them. Its radiological diagnosis is mainly suggested by location. However, several cases of CG with atypical locations have been described, illustrating that CG is not limited to the third ventricle, and should be considered in the list of radiological differential diagnosis for intraventricular masses. We present here a case of CG that was found in the fourth ventricle.
脊索样胶质瘤（CG）是一种罕见的脑肿瘤，以其在第三脑室的特征性位置而闻名。已经描述了广泛的放射学表现，其中很少有共同特征。其放射学诊断主要由位置提示。然而，已经描述了几例具有非典型位置的CG病例，说明CG不限于第三脑室，在脑室内肿块的放射学鉴别诊断列表中应予以考虑。我们在此呈现一例在第四脑室发现的CG病例。
