报告１０６例脑膜瘤患者，其中５８．３％纤维母细胞型和６３．６％过度型ＣＴ均一强化；７３．３％血管母细胞型和６２．５％合体型ＣＴ非均一强化；血管母细胞型和恶性脑膜瘤瘤周水肿率高，过度型和纤维母细胞型钙化率高。ＣＴ在一定程度上可提示脑膜瘤的病理类型。本组重度瘤周水肿的肿瘤，术中有３例发生急性脑膨出，术前应用甘露醇、激素脱水对其有一定的预防作用。 106 cases of meningiomas were reported, of which 58.3% were fibroblast-type and 63.6% were hypercontrast-enhanced CT; 73.3% were hemangioblast-type and 62.5% were combined with non-uniform CT; hemangioblasts The rate of peritumoral edema was high in type and malignant meningioma, and the excessive type and fibroblast type calcification rate were high. CT can, to some extent, suggest the pathological type of meningioma. In this group of tumors with severe peritumoral edema, there were 3 cases of acute encephalocele in operation. Preoperative application of mannitol and hormone dehydration had a certain preventive effect.
