目的　观察实性、实性部分囊变和完全囊性等不同形态的前庭神经鞘瘤的病理学结构。方法　对不同形态肿瘤组织进行光镜和电镜观察。结果　肿瘤形态虽有不同 ,但光镜下多数肿瘤间质中可见到毛细血管扩张、变性或血窦及血窦内红细胞瘀积 ,超微结构基本相似。结论　肿瘤毛细血管扩张、变性 ,血窦内瘀血等造成肿瘤内反复出血 ,可能是肿瘤表现为不同形态的组织学基础 Objective To observe the pathological structure of vestibular schwannoma with different forms such as solid, solid partial cystic changes and complete cystic lesions. Methods Light microscope and electron microscopy were performed on different tumor tissues. Results Although the tumor morphology is different, most of the tumor interstitial light microscope can see the telangiectasia, degeneration or sinusoids and sinusoidal red cell hoarding, ultrastructure similar. Conclusion Tumor telangiectasia, degeneration, hemorrhage in the sinusoids, etc. cause repeated bleeding in the tumor, which may be the histological basis of the tumor’s appearance in different forms.
