title: Hypertension and a Large pulsatile neck mass: A Case of Malignant Glomus Vagale Tumour.
abstract: This teaching case report represents an unusual example of a neck mass in a previously healthy individual. The presence of a new neck mass is a relatively common head and neck problem and requires a full work up including a complete history and physical examination. With respect to our patient, thorough history taking, physical examinations and specific investigations led to the diagnosis of a malignant and functionally active paraganglioma. Vagal paraganglioma themselves are rare tumours and account for only 5-25% of all paragangliomas in the head and neck region. The presence of a malignant, functionally active, catecholamine-secreting paraganglioma is even rarer and accounts for only 1-3% of all reported glomus vagale tumours. This case report illustrates the need to carefully monitor all neck masses for changes in size, for any distortion to surrounding structures, and their given function.
