摘要: 目的:报告一例罕见的迷路内听神经瘤。研究方法:根据病史,检查所见及影像学的表现,详细分析,得出诊断,提出治疗意见;并复习文献。结果:经多方讨论,排除其它疾病的可能,最后诊断为迷路内听神经瘤。以手术切除为最佳治疗方法,因病人不愿意手术,最后采用r-刀治疗。结论:迷路内听神经瘤无典型临床症状,钆强化MRI检查是该病的最佳诊断工具,早期肿瘤局限于迷路内且无严重眩晕症状时可以观察,若病人有严重的眩晕症状,或肿瘤向迷路外漫延,应手术切除肿瘤或采用r-刀治疗。

Abstract: Objective The present study reports a patient with a rare acoustic neuroma that aroses from the cochlea. Methods In order to diagnose and treat, a detailed analysis is performed according to the case history, physical examination and radiographic findings {CT (computerized tomography) and MRI (magnetic resonance imaging) scanning}. And literature review. Results Some specialists discuss this case. Consequently, intralabyrinth acoustic neuroma is identified so that other possibilities are excluded. Surgical treatment is regarded as the optimal choice. Because the patient doesn’t agree with it, gamma knife (γ-knife) is used at last. Conclusions Intralabyrinth acoustic neuroma has no typical clinical symptoms, and gadolinium enhanced MRI examination is its best diagnostic tool. Early tumors confine to the labyrinth and no severe dizziness symptoms can be observed. If the patient has severe vertigo, or tumors spread out of the labyrinth, surgical resection of the tumors or the use of r-knife treatment should be applied.
