Rarely, patients can present in cardiac arrhythmia if the carotid sinus is stimulated by compression from the tumour.Ĭarotid body tumours can be managed conservatively with active monitoring via serial imaging, or require surgical excision in a specialised unit with both ENT and vascular input. Carotid paragangliomas are slow growing, but can become large enough to compress surrounding cranial nerves, leading to palsies. 4).Ī carotid body tumour will present as a pulsatile painless neck lump, often with a bruit present on auscultation*. The carotid body is made up of a cluster of neuroendocrine cells, whereby sporadic (or hereditary) mutations lead to the formation of paragangliomas (Fig. Carotid body tumours (also known as a carotid paragangliomas) are benign neuroendocrine tumours that arise from the paraganglion cells of the carotid body.
