A Case of Metastatic Lung Cancer Presenting with Isolated Hypoglossal Nerve Palsy

ABSTRACT

The peripheral hypoglossal nerve palsy is caused by carotid aneurysm, vascular entrapment, local infection, trauma, neck radiation, and tumors in the neck, retropharyngeal spaces, and basilar area of skull. A basilar skull lesion may rarely involve the hypoglossal nerve alone. We report a 58-year-old man with isolated hypoglossal nerve palsy due to metastasis of lung cancer at the skull base.
