内听道海绵状血管瘤(附1例报告并文献复习)

目的：探讨内听道海绵状血管瘤的诊断和治疗方法。方法：分析1例术后病理确诊为内听道海绵状血管瘤患者的临床表现、听力学、影像学及病理诊断等临床资料，并经扩大迷路进路行肿瘤切除术。结果：术后恢复良好，无面瘫、脑脊液漏等并发症发生，术后病理确诊为内听道海绵状血管瘤。结论：原发于内听道的海绵状血管瘤是一种极为罕见的内听道良性占位性血管性病变，和内听道其他常见的肿瘤如听神经瘤、面神经瘤等在临床表现、听力学及影像学上有许多相似之处，但也有其自身特点，确诊有赖于术后病理检查，结合临床表现和影像学（CT、MRI）特点，可为早期发现、选择合适的治疗方法提供信息。早期手术，其全切率及面、听神经功能的保存率较高。

Cavernous hemangioma in internal auditory canal:Case report and review of the literature

Objective:To discuss the diagnosis and treatment of cavernous hemangioma in internal auditory canal(IAC).Method:One case of cavernous hemangioma in IAC was diagnosed and treated. The clinical data including clinical manifestation, hearing tests, imaging findings and pathology diagnosis were reviewed.Result:The tumor was totally removed by translabyrinthine approach without any complication, such as facial paralysis or cerebrospinal fluid otorrhea.Conclusion:Cavernous hemangioma of the IAC have arisen from vascular plexuses surrounding Scarpa's ganglion. It is a rare occupying leision in IAC of benign nature. Early diagnosis depends on clinical manifestation and imaging findings. Subtle radiographic findings may help in differentiating these lesions from schwannomas. The ultimate diagnosis is made on pathologic examination of the tissues after surgical extirpation.
