Analysis of 4 Cases of Middle Ear Meningioma and Literature Review

目的：探讨4例中耳脑膜瘤病例的临床表现、影像学表现及治疗方案。方法：回顾总结我院中耳脑膜瘤住院患者4例，分析其临床表现、影像学表现及治疗方案。结果：病例1及病例4患者鼓室内软组织影孤立，与颅内结构无关系，诊断为颅外原发性脑膜瘤；病例2及病例3患者软组织影与颅脑结构相连，诊断为颅外继发性脑膜瘤。结论：中耳异位脑膜瘤是一种罕见的占位性病变，易引发严重颅内外并发症，严重时可导致患者死亡。对于诊断明确的中耳脑膜瘤，应及早进行手术治疗，彻底清除病变，可达到治愈的效果。Objective: To explore the clinical manifestations, imaging findings, and treatment plans of four cases of middle ear meningioma. Method: In this study, we conducted a retrospective review of 4 cases of middle ear meningioma patients admitted to our hospital, analyzing their clinical manifestations, imaging features, and treatment plans. Result: Patients 1 and 4 had isolated soft tissue shadows in the tympanic cavity, which were not related to intracranial structures, and were diagnosed as primary extracranial meningiomas; Cases 2 and 3 were diagnosed with extracranial secondary meningioma due to the connection between soft tissue shadows and cranial structures. Conclusion: Middle ear ectopic meningioma is a rare space-occupying lesion that can easily cause serious intracranial and extracranial complications, and in severe cases, can lead to patient death. For diagnosed middle ear meningiomas, early surgical treatment should be performed to thoroughly remove the lesion, which can achieve a curative effect.
