CT表现为非典型性非恶性脑膜瘤的病理学探讨

A study on pathology of non-malignant meningiomas with CT atypical characteristics

我们对45例CT表现为非典型病理诊断为非恶性的脑膜瘤，采用细胞核仁组成区嗜银蛋白技术进行观察。结果表明．其中48．9%的Ⅱ级脑膜瘤（WHO）分级）虽非恶性，但细胞核仁组成区嗜银蛋白的数量、大小分布及异常形态变化与Ⅰ级者有明显差异，两者呈直线相关关系。提示CT表现为非典型性Ⅱ级脑膜瘤有明显的潜在增殖能力。推断可藉此预测CT表现为非典型性非恶性脑膜瘤的复发机率。

45 cases of non-malignant meningiomas with CT atypical characteristics was obscredby silver-staining of nucleolus organizer regiuns technic. Result showed that 48.9% of grade Ⅱ(WHO) meningiomas were more different than grade Ⅰ in the field of counts, size and abnorma shap.and both were linear correlation. To point out that the Ⅱ grade meningiomas with CT atypical characteristies were incubative proliferative ability. The rates of reccurrence in the CT atypical characteristiesnon-matignant meningiomas may be calculated on the basis of these.
