目的：讨论室管膜瘤病理形态特征。方法：对我们在外检中遇到的37例堂管膜瘤临床和形态学特征作回顾性分析。结果：37例中男18例、女19例，平均发病年龄223岁。肿瘤在显微镜下最显著的形态特点为瘤细胞围绕血管排列成血管心菊形团.在血管周围显示无核的空景区（94.6％）及在肿瘤内可见豹皮状元核区（973％）。部分病例在肿瘤内可见室管膜裂隙（20.0％）。结论：室管膜瘤可发生于中枢神经系统的各个部位，起源于脑室管膜和脊髓中央管覆盖上皮细胞，病理分为乳头型、上皮型及多细胞型，还应与少技胶质细胞瘤相鉴别。
Objective: To discuss the pathological features of ependymoma. Methods: We retrospectively analyzed the clinical and morphologic features of 37 cases of medulla tumor that we encountered in the external examination. Results: There were 37 males and 19 females with an average age of 223 years. The most prominent morphological features of the tumor under the microscope were that the tumor cells arranged around the blood vessels into a vascular heart-shaped chrysanthemum cluster. Nucleus-free empty spots (94.6%) were seen around the blood vessels and leopard skin-like nuclear regions (973%) were visible in the tumor. In some cases, ependymosomal fissures were seen in the tumor (20.0%). Conclusion: Ependymomas can occur in various parts of the central nervous system, originating in the ventricles of the ventricles and the central canal of the spinal cord covering the epithelial cells. The pathology can be divided into papillary, epithelial, and multicellular types, and should also be associated with oligodendrocytes. Differentiating tumors.
