Falcotentorial meningiomas arise along the junction of the falx cerebri and the tentorium cerebelli. The authors present a woman in her 60s with an incidentally discovered falcotentorial meningioma, approximately 3 cm in diameter, resected with a torcular craniotomy and posterior interhemispheric approach. The galenic complex was dissected away from the tumor. In the final view, the bilateral internal cerebral veins and basal veins of Rosenthal were seen. A Simpson grade I resection was achieved. The patient experienced transient contralateral hemianopsia and was discharged home. At 1-year follow-up, her neurological examination findings were unremarkable, and there was no radiographic evidence of tumor.

小脑幕镰旁脑膜瘤起源于大脑镰和小脑幕的交界处。作者报告了一名60多岁的女性，偶然发现直径约3厘米的小脑幕镰旁脑膜瘤，采用窦汇开颅术和后纵裂入路进行切除。将大脑大静脉复合体从肿瘤上分离。最后可见双侧大脑内静脉和罗森塔尔基底静脉。实现了辛普森一级切除。患者出现短暂性对侧偏盲，随后出院回家。在1年的随访中，她的神经学检查结果无异常，影像学检查也未发现肿瘤迹象。视频可在此处查看：https://stream.cadmore.media/r10.3171/2021.4.FOCVID2125 。
