title: A functioning catecholamine-secreting vagal body tumor. A case report and review of the literature.
abstract: There are few cases of catecholamine-secreting paragangliomas of the neck reported in the literature, most of these being of the carotid body and glomus-jugulare type. This report cites the second case of a functioning vagal body tumor secreting norepinephrine predominantly and producing labile hypertension and symptoms of pheochromocytoma. A brief update on vagal body tumors and a review of the functioning paragangliomas of the head and neck are also presented.
