ABSTRACT: 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.
