目的 :探讨核沟作为室管膜瘤细胞学诊断指标的意义。方法 :观察了 31例经组织学证实为室管膜瘤的术中冰冻切片的组织细胞涂片 ,统计分析每例瘤细胞出现核沟、室管膜瘤菊形团、血管周假菊形团的频率。结果 :74.2 % (2 3/ 31)发现有核沟 ,77.4% (2 4/ 31)见有室管膜瘤菊形团 ,35 .5 % (11/ 31)出现有血管周假菊形团。结论 :核沟可作为除室管膜瘤菊形团、血管周假菊形团外的又一室管膜瘤细胞学特点。
Objective: To investigate the significance of nuclear ditch as a cytologic diagnostic indicator of ependymomas. Methods: Thirty-one histological smears of intraoperative frozen section of ependymoma confirmed by histological examination were observed. Statistical analysis was made on the appearance of nuclear groove, ependymoma, Frequency of. RESULTS: There were 74.2% (2/3 / 31) of the cases with nuclear ditch, 77.4% (24/31) with ependymoma, 35.5% (11/31) . Conclusion: Nuclear ditch can be used as a cytologic feature of the additional ependymoma in addition to the ependymal neovascularization and pseudoephedrons.
