起源于大脑镰-小脑幕交界处的脑膜瘤(简称镰-幕交界脑膜瘤)非常少见,到1995年文献中仅见38例报道。了解此处解剖结构的特点有利于切除该区肿瘤,减少或避免术后并发症。本文将我院治疗的3例镰-幕交界脑膜瘤作一介绍。 病例介绍 例1.女,44岁,头痛5年,走路不稳2年,并有记忆力明显减退。入院前4个月因车祸致脑挫伤入院,头部CT检查时,发现小脑幕切迹处有一7cm×5cm×5cm的巨大肿瘤影。对比剂增强明显,并伴有梗阻性脑积水。血管造影见镰-幕交界处肿瘤染色。诊断
Meningiomas, which originate from the falx-cerebellar junction, are rare, with only 38 reported in the literature in 1995. Understanding the characteristics of the anatomy here is conducive to the excision of the area of the tumor, reduce or avoid postoperative complications. This article will be treated in our hospital 3 sickle - curtain junction meningioma for an introduction. Cases introduced 1. Female, 44 years old, headache for 5 years, 2 years walking instability, and memory was significantly reduced. Four months before admission due to a car accident caused by brain contusion admitted to the hospital, the CT examination of the head, found a small tentorium notch 7cm × 5cm × 5cm huge tumor shadow. Contrast agent increased significantly, accompanied by obstructive hydrocephalus. Angiography see sickle - curtain junction tumor staining. diagnosis
