目的:提出并探讨鞍膈脑膜瘤的诊断、鉴别诊断及其显微外科手术治疗。方法:8年间经手术及病理证实的鞍膈脑膜瘤10例,其中男性5例,女性5例,平均年龄43岁。根据肿瘤与鞍隔的关系可分为3型,即鞍上型、鞍内型和鞍内鞍上型。10例均采用Yasargil切口行显微外科治疗。结果:10例中8例行肿瘤全切除,2例行肿瘤大部分切除,7例痊愈,2例好转,仅1例死亡。结论:鞍隔脑膜瘤为发生于鞍膈及其附近的肿瘤,肿瘤可向鞍内或鞍上生长,其临床表现为进行性视力下降,而内分泌功能障碍却很少见,计算机体层摄影(CT)及磁共振成像(MRI)检查见鞍内及鞍上有肿块阴影,易误诊为垂体腺瘤,显微外科治疗有益于肿瘤全切除。
Objective: To propose and discuss the diagnosis, differential diagnosis and microsurgical treatment of saddle meningioma. Methods: There were 10 cases of saddle meningioma confirmed by operation and pathology in 8 years, including 5 males and 5 females, with an average age of 43 years. According to the relationship between tumor and septum can be divided into 3 types, namely saddle type, saddle type and saddle type saddle. Ten cases were treated with Yasargil incision microsurgery. Results: Totally resected tumors were performed in 8 of the 10 cases. Most of the tumors were resected in 2 cases, 7 cases recovered, 2 cases improved and only 1 case died. Conclusion: The septum meningioma is a tumor that occurs in the septum and its vicinity. The tumor can grow into the saddle or the saddle. The clinical manifestations are progressive visual loss and endocrine dysfunction are rare. Computed tomography CT) and magnetic resonance imaging (MRI) examination showed saddle and saddle with lump shadow, easily misdiagnosed as pituitary adenoma, microsurgery is beneficial for tumor resection.
