Glossopharyngeal neuralgia (GN) is a rare pain syndrome caused by compression of the glossopharyngeal nerve. It is typically idiopathic and often goes misdiagnosed because of its similarities to trigeminal neuralgia. Vago-glossopharyngeal neuralgia, an even rarer subset of GN, occurs when the pain is accompanied by syncope and/or arrhythmia. Here, we present the case of a 54-year-old man with oropharyngeal cancer that metastasised to areas within his left carotid sheath. He presented with numerous intermittent episodes of pain, accompanied by vagal episodes. While this presentation is similarly described in prior case reports, our case is unique in that the syndrome occurred as a direct sequelae of a metastatic tumour completely encasing the left internal carotid artery.
