Paragangliomas could be localized from the skull base to the pelvic floor. Tympanic localization represents the most common benign tumor of the middle ear. Diagnosis is based on clinical signs with a great contribution of radiology. A 40-year-old male presented with isolated tinnitus of the right ear evolving for 18 months. Examination revealed a red bulging right-sided tympanic membrane and a conductive hearing loss. Tomodensitometry and Magnetic resonance imagery showed findings in favor of a right jugular tympanic paraganglioma. The tumor was classified type B according to FISCH classification. The patient underwent surgery consisting in tympanotomy using a retro auricular access route. The postoperative course was uneventful. There was no recurrence during the one-year follow-up. Jugular tympanic paraganglioma diagnosis is guided by a combination of epidemiological, clinical and radiological features. Treatment is still not consensual, but surgery still have its indications in localized forms of head and neck paragangliomas (HNP´s).
副神经节瘤可从颅底定位到骨盆底部。鼓室定位是中耳最常见的良性肿瘤。诊断基于临床体征,并结合影像学的巨大贡献。一名 40 岁男性出现右侧耳鸣,持续 18 个月。检查发现右侧鼓膜红肿膨出,传导性听力损失。断层扫描和磁共振成像显示有利于右侧颈鼓副神经节瘤的发现。根据 FISCH 分类,肿瘤被分类为 B 型。患者接受了手术,采用经耳后入路的鼓室切开术。术后过程顺利。在一年的随访中没有复发。颈鼓副神经节瘤的诊断是通过流行病学、临床和影像学特征的综合来指导的。治疗方法仍存在争议,但手术仍然适用于头颈部副神经节瘤(HNP)的局限性形式。
