A Case of Oropharyngeal Carotid Space Mass Presenting with Isolated Hypoglossal Nerve Palsy

The isolated hypoglossal nerve palsy is less frequently seen, but occasionally it appears as the initial or solitary sign of an intracranial or extracranial space-occupying lesion or a vascular abnormality of the internal carotid artery. We present a 55-year-old woman with isolated hypoglossal nerve palsy due to an oropharyngeal carotid space mass.
