Hemangioma is a common vascular neoplasm that arises in the head and neck regions but is rare in the petrous bone. We report the first case of a solitary cavernous hemangioma in the mastoid antrum. A 68-year-old woman visited our hospital with a complaint of tinnitus without any other symptoms. Tinnitus of the right ear occurred especially when the patient yawned or swallowed. Both tympanic membranes appeared normal on otoscopic examination. On pure-tone audiometry, mild hearing loss up to 25 dB was detected in the right ear. Temporal bone computed tomography revealed a 7.0 mm × 4.5 mm × 5 mm, solitary soft tissue mass in the aditus ad antrum. Excisional biopsy was performed under general anesthesia through the canal wall as in a mastoidectomy. The mass was completely removed without any bleeding or ossicular chain damage. The mass was confirmed as a cavernous hemangioma. During follow-up, the patient's tinnitus and right low-tone hearing loss improved. No solitary hemangioma of the mastoid antrum has been reported previously. Surgical excision of the lesion appears to be proper treatment to achieve pathologic confirmation along with resolution of symptoms.
血管瘤是一种常见的血管性肿瘤，多发生于头颈部，但发生于岩骨者罕见。我们报告首例发生于乳突窦的孤立性海绵状血管瘤。一位 68 岁女性因耳鸣而就诊，无其他症状。右侧耳耳鸣尤其在患者打哈欠或吞咽时出现。耳镜检查双侧鼓膜正常。纯音测听显示右耳有 25dB 以内的轻度听力损失。颞骨 CT 显示在外耳道入口处有一个 7.0mm×4.5mm×5mm 的孤立软组织肿块。在全身麻醉下通过乳突根治术入路进行了切除活检。肿块完整切除，无出血或听骨链损伤。肿块被确认为海绵状血管瘤。随访时，患者的耳鸣和右低频听力损失改善。此前尚未报道过孤立性乳突窦血管瘤。手术切除病变似乎是一种适当的治疗方法，既能达到病理证实，又能缓解症状。
