Glomus Jugulare Tumors
摘要
First described in 1840 by Guild, glomus tumors (GTs) are rare, benign and slow-growing lesions arising from paraganglia of the chemoreceptor bodies located at the carotid body and carotid artery bifurcation, jugular bulb, tympanic plexus and vagal ganglia [1–3]. They can also be located within the tympanic branch of the glossopharyngeal nerve (Jacobson’s nerve) or the auricular branch of the vagal nerve (Arnold’s nerve) [4, 5]. Rarely, GTs, also known as chemodectomas or paragangliomas (PGL), may be associated with dopamine secretion in about 1–3% of cases [6].
