A 70-year-old woman was admitted because of left facial nerve palsy. Brain magnetic resonance imaging showed a mass lesion with a well-enhanced margin in the left temporal bone. A computed tomographic scan of the chest showed a lung mass in the left lower lobe, which was thereafter diagnosed as adenocarcinoma. An immunohistochemical examination of the tissue specimen obtained from the left temporal bone revealed evidence of metastatic adenocarcinoma from the lung. No other metastatic lesions including separate site of bone were seen. This is a very rare case of lung cancer with facial nerve palsy as the first sign of onset due to a metastatic temporal bone tumor.
一名70岁女性因左侧面神经麻痹入院。脑部磁共振成像显示左侧颞骨有一肿块，边缘强化明显。胸部计算机断层扫描显示左下叶有一肺部肿块，随后被诊断为腺癌。对取自左侧颞骨的组织标本进行免疫组化检查，发现有来自肺部的转移性腺癌证据。未见其他转移病灶，包括其他部位的骨转移。这是一例非常罕见的肺癌病例，以面神经麻痹作为颞骨转移瘤首发症状。
