Malignant tumors of the temporal bone are rare. They include a wide histological variety. They are mostly primary tumors with an estimated incidence of 0.8-1.0 per 1,000,000 inhabitants per year [1]. Metastases form an uncommon subgroup. The clinical features of these temporal bone metastases are nonspecific and predominantly consist of hearing loss, vertigo, facial palsy, tinnitus, headache, otalgia or otorrhoea [2]. The aim of our publication is to report a rare case of metastasis in the temporal bone as initial manifestation of lung cancer. Our patient was a 44-year-old man who presented for a right mastoid swelling with a grade VI right facial nerve palsy. Imaging and biopsy confirmed the diagnosis of small cell lung carcinoma petrous metastasis. The treatment was palliative. An osteolytic lesion of the temporal bone in an elderly patient may fit with a primary tumor of the temporal bone. It must, also, suggest the diagnosis of metastasis. The malignant tumor most frequently responsible is breast cancer, but lung cancer must also be considered in smoking patients.
颞骨恶性肿瘤较为罕见。其包含广泛的组织学类型。这些肿瘤主要为原发性肿瘤，估计每年每 100 万人中有 0.8-1.0 例[1]。转移瘤为一不常见的亚组。这些颞骨转移瘤的临床特征无特异性，主要表现为听力损失、眩晕、面瘫、耳鸣、头痛、耳痛或耳漏[2]。我们发表的目的是报告一例肺癌首发表现为颞骨转移的罕见病例。我们的患者是一名 44 岁男性，因右侧乳突肿胀伴 VI 级右侧面神经麻痹就诊。影像学和活检证实为小细胞肺癌岩骨转移。治疗为姑息性的。老年患者颞骨溶骨性病变可能符合颞骨原发性肿瘤。此外，还应提示转移瘤的诊断。最常引起恶性肿瘤的是乳腺癌，但在吸烟患者中还必须考虑肺癌。
