Metastatic carcinoma of the temporal bone is rare and often not recognized because it can be either asymptomatic or overshadowed by other metastases late in the disease course. Metastatic evaluation does not usually include temporal bone imaging, and the temporal bone is not routinely sectioned at autopsy, further contributing to unreported metastases. Two case reports of metastasis to the internal auditory canal are presented, as well as a review of 139 such patients reported in the world literature. Analysis includes types of tumor, specific sites of secondary malignancy within the temporal bone, and manifestations. Although uncommon, metastatic carcinoma of the temporal bone must be included in the different diagnosis of any cochleovestibular or facial nerve disorder.
颞骨转移性癌罕见，常不被识别，因为它可能无症状，或在疾病晚期被其他转移灶掩盖。转移灶评估通常不包括颞骨成像，且尸检时颞骨通常不常规切片，这进一步导致转移灶未被报告。本文介绍了两例内耳道转移的病例报告，并对世界文献中报道的139例此类患者进行了综述。分析包括肿瘤类型、颞骨内继发性恶性肿瘤的具体部位及表现。尽管罕见，但颞骨转移性癌必须纳入任何耳蜗前庭或面神经疾病的鉴别诊断中。
