Most meningiomas grow intracranially, and primary intraosseous meningioma is rarely reported. We present two rare surgical cases of giant intraosseous meningothelial meningioma. The first patient was a 35-year-old male with parietal skull deformity without neurological symptoms. Total resection was successful. The origin was the parasagittal intraosseous layer, and the superior sagittal sinus was partially opened. The second patient was a 20-year-old female with a slightly upward protrusion of the frontal skull without pain or neurological deficits. The lesion was totally resected, and the origin was the parasagittal intraosseous layer invading into the dura matter and subcutaneous layer. The clinical management of these cases presented a surgical challenge because of detachment and repair from venous sinuses. The current report provides surgical tips for such rare diseases and is a good reference for the future treatment of similar diseases.
大多数脑膜瘤生长于颅内，原发性骨内脑膜瘤鲜有报道。我们呈现两例罕见的巨大骨内脑膜皮型脑膜瘤手术病例。首例患者为一名35岁男性，顶骨颅骨畸形，无神经症状。全切成功。肿瘤起源于矢状窦旁骨内层，部分打开上矢状窦。第二例患者为一名20岁女性，额骨稍向上突出，无疼痛或神经功能缺损。病变被完全切除，起源为矢状窦旁骨内层，侵犯硬脑膜和皮下层。由于与静脉窦的分离和修复，这些病例的临床处理带来了手术挑战。本报告提供了针对此类罕见疾病的手术技巧，为未来类似疾病的治疗提供了良好参考。
