矢状窦旁是脑膜瘤的好发部位。脑膜瘤虽然在组织学上多属良性，但有局部浸润倾向，易侵犯上矢状窦壁及窦腔，肿瘤全切难度较大。对受累的矢状窦处理不彻底是术后复发的主要原因。我院自１９７８年３月至１９９７年２月共收治矢状窦旁脑膜瘤６４例，均进行了手术，效果满意... Sagittal sinus is a good site for meningioma. Although meningioma is mostly benign in histology, but there is a tendency of local infiltration, easy to invade the superior sagittal sinus wall and sinus cavity, the tumor is difficult to cut. Incomplete treatment of sagittal sinus involvement is the main reason for postoperative recurrence. In our hospital from March 1978 to February 1997, a total of 64 cases of sagittal sinus meningioma were treated. All of them were performed with satisfactory results.
