title: Hearing loss due to metastasis of gastric cancer to temporal bone: A case report.
abstract: Metastatic temporal bone tumors are rare, and tend to be asymptomatic. The clinical symptoms consist of aural discharge, bleeding, hearing loss and facial nerve paresis. The most common origin of the metastasis is breast cancer, and other sites of the primary tumor include the thyroid gland, brain, lungs, prostate and blood. Clinical reports of hearing loss due to gastric cancer metastatic to temporal bone are rare. In the present study, a case of gastric cancer metastasis to temporal bone without other organ involvement is described. The patient presented with the symptom of hearing loss, and the metastatic tumor was diagnosed by radiological imaging, including magnetic resonance imaging, computed tomography and bone scan.
