Carotid body tumours cause characteristic splaying of the internal and external carotid arteries, known as 'Lyre Sign'. Vagal paragangliomas are rare tumours that arise from glomus cells along the length of the vagus nerve. We present a case in which a vagal paraganglioma has arisen from the vagus nerve at the carotid bifurcation, and has mimicked the 'Lyre Sign' of a carotid body tumour.
