Neurogenic cough has been likened to a vagus nerve neuropathy in a similar way that trigeminal neuralgia is a trigeminal nerve neuropathy. Both cause intermittent sensory phenomena in their distribution and can be ameliorated with neuropathic medications. We demonstrate that neurogenic cough, like trigeminal neuralgia, may be caused by a vascular compression of its nerve root. A proposed mechanism of this type of neurogenic cough is presented along with a potential diagnostic paradigm for these patients.
