摘要
目的 探讨影响星形细胞瘤瘤周水肿的因素 ,研究CT对星形细胞瘤诊断和鉴别诊断的价值。材料与方法 分析 12 0例经病理证实的脑星形细胞瘤的瘤周水肿与肿瘤恶性程度、部位和大小的关系。结果 Ⅰ级星形细胞瘤的瘤周水肿轻 ,Ⅱ～Ⅳ级瘤周水肿明显 ;位于皮髓交界区的肿瘤 ,瘤周水肿最明显 ;肿瘤越大 ,水肿越明显。结论 Ⅱ°以上的瘤周水肿 ,97.4%为Ⅱ～Ⅳ级星形细胞瘤 ;肿瘤直径大于 5 .7cm 。
Objective To study the factors affecting the edema around astrocytoma, and to evaluate CT scan in diagnosing and differentiating astrocytoma.Materials and Methods The relationship between the edema and the malignant degree, location, size of the tumor in 120 cases with pathologicallyproved astroglioma was analyzed.Results Grade Ⅰ astroglioma demonstrated mild edema, while grade Ⅱ～Ⅳ showed marked edema. Marked edema was found in tumors located in the linking area of white and gray matter. The greater the tumor size was, the more severe edema it carried.Conclusion 97.4% cases with Ⅱ° and Ⅲ° edema are grade Ⅱ～Ⅳ astroglioma, and most tumors over 5.7cm in diameter are grade Ⅱ～Ⅳ astroglioma.
